SWALLOWTAIL BUTTERFLIES ON ABACO
Uli Nowlan has had two beautiful swallowtail butterfly species in her garden at Treasure Cay. These are absolute stunners, with great camerawork to capture the details.
A fast-flying butterfly in a fetching shade of orange designed to be off-putting to avian predators. If the colour fails as a deterrent, these butterflies are unpleasant to eat (supposedly), so birds learn to leave them alone.
OTHER BUTTERFLIES IN THIS SERIES
At first glance the Common Buckeye Butterfly Junonia coenia looks unpromisingly drab. However, like many butterfly species, the outside appearance is only one side of the story, a facade to enable it to blend in with the scenery. As the header image suggests, this creature has a more more flamboyant and colourful side to it – a feature not confined to butterflies, and extending even to humans…
The bright eye-spots of the buckeye, for which it is named, are designed to deter predators, as much as for decorative purposes. Birds, in particular, are thought to be put off by a creature apparently possessing 3 pairs of eyes.

The black and orange patterns of this butterfly are a reminder to predators of the toxicidity of its stripy caterpillar and birds tend to leave them alone. Just in case. The markings are also similar to other butterflies that are poisonous – for example the Monarch. Tip of the hat to Wiki for the information that “this species belongs to the ‘orange’ Batesian mimicry complex”. Me neither! It is where an innocuous species resembles a noxious one in order to discourage predators without going to the bother of actually developing its own ‘on-board’ toxins.
The gulf fritillary is common on Abaco, as elsewhere in the Bahamas. I particularly fond of the photo below, in which the whole feeding apparatus can be seen. I haven’t done my homework, I’m afraid. If anyone wants to provide the technical terms (mouth? proboscis? tongue-thing?), that would be welcome. Please use the comment box to spread enlightenment.
FURTHER BUTTERFLIES YOU MAY ENJOY

The Zebra Heliconian butterfly Heliconius charithonia is also know as the Zebra Longwing. These striking butterflies roost nightly in large colonies, a species behaviour that is believed to be a protective measure against predation, providing safety in numbers (or at least reducing the probabilities that you will be the one to be eaten). In 1996 the Zebra Longwing was appointed the State Butterfly of Florida.

The Bahamas ‘does’ extremely nice stamps, in particular ones featuring the rich and varied wildlife of the islands. The islands spread from the subtropical climates of the north, on a level with Florida, to the near-tropical islands of the south. This ensures plenty of scope for designing pretty sticky bits of paper to stick onto other bits of paper. One of the small pleasures in life, near-lost to the tyranny of the email…
The sets of wildlife stamps are issued by the Bahamas Post Office. I’ll add to this collection piecemeal (including some from my own modest collection). The very latest commemorative issue heads the display.

February 2012: WWF Flamingo Issue
Best seen on Inagua, the island where they breed. Less often found elsewhere, and sadly now only as occasional ‘vagrants’ on Abaco. Flamingo post with wonderful pictures of adults, babies and nests HERE
Found mainly on Abaco (the resident underground nesting variety) and Inagua (conventional nesters), where they breed. Small groups are now found elsewhere, e.g. Nassau, where there is a local monitoring programme, but I’m not sure that there is evidence of breeding there. Any info welcome… One (of several) lavishly illustrated parrot posts HERE

OTHER BIRD SPECIES
The KIRTLAND’S WARBLER is one of the rarest birds of the Bahamas, a winter resident that breeds only in a small area of Michigan. The entire population is numbers only a few thousand birds. The number of sightings annually on Abaco is very small – fewer than a dozen, and in some years none at all. Increasing knowledge about their favourite haunts is now improving the recording rate. I know of two seen this year, on the same day… a birder’s lifetime achievement.

It’s hard to resist another fly-past for the Atala Hairstreak Butterfly Eumaeus Atala . So I won’t. Once seen, never forgotten. They are small wonders, with their plump orange abdomens and their striking blue-dotted motif; obvious candidates for a signature Rolling Harbour logo for insect posts.
It is rare to see the inside of an Atala’s wings. In flight they tend just to look black; then they land with precision and closed wings (zeugma score!). In sunshine the spots of the feeding Atala shine out like small LEDs. They very rarely open their wing to reveal the velvety blue upper sides.As I watched the single Atala, a second one arrived and almost immediately ‘jumped’ the first. By which I mean that, for a few seconds, the new arrival ‘covered’ the feeding Atala in every sense of the word. Please consider this a blurry study of the upper side of an Atala’s wings, and politely ignore the intrusive circumstances. This is not a scandal blog. Yet. Mere moments later, it was all over **. I made my excuses and left.
These events may have piqued your interest in the life cycle of the Atala. Some months ago I posted in detail about this, with the whole process illustrated from eggs, larvae, caterpillar and chrysalis to the emergent butterfly. At the end of the post are some helpful links. CLICK LIFECYCLE OF THE ATALA HAIRSTREAK

BLOOMING MARVELLOUS: FLOWERS OF ABACO
The flowers and plants below were mostly photographed in the grounds of The Delphi Club, Abaco or nearby. I expect most or many are already securely on the SD chips or hard drives of every visitor to an agreeably floral place like the Bahamas. Who can resist a pretty flower? I have confessed in earlier plant-based posts (links below) to a certain lack of aptitude around flowers. They just… are. Let’s see how this pans out – corrections and (for the last two) IDs welcome.
FIRECRACKER PLANT RusseliaMARSH FLEABANE (WITH HONEY BEE) PlucheaHORSERADISH TREE (WITH CUBAN EMERALD HUMMINGBIRD) Moringa oleiferaBISMARCK PALMBANANASThese were growing just outside our bedroom. Pity they weren’t quite ripe…
I’m beginning to struggle now. The next two plants are probably completely obvious, but I am losing my floral grip. Suggestions welcome via the comment box or email (Bridget on Tilloo, that means you…)
STOP PRESS ID within 24 hours, thanks to Nick Kenworthy who says via the comment box that this bright pink one “is loosely referred to as the Orchid tree (or Hong Kong Orchid Tree) as the blooms are very like an orchid but it comes on a tree rather than a plant”. I’ve checked my cheat books, where it is named Bauhinia pupurea, aka Orchid Tree, Butterfly Tree or (from the leaf shape) Bull Hoof Tree. The tree originates from India and Southeast Asia. Nick has undoubtedly nailed it, for which many thanks. One more to go…
STOP PRESS 2 Nick has solved the second ID as well. His interesting information about this striking waxy plant can be seen in detail in the comments below. The answer, in a word, is ‘Jatropha’, of which there are a great many varieties – and quite a number of informal names, most of which (‘Firecracker'; ‘Star of Bethlehem’) are confusingly assigned to other plant species as well. It doesn’t feature in either of my Caribbean plant /tree reference books, so my amateur eyes didn’t actually let me down this time… This plant (there was were two of three) was in a small park area by the beach at Treasure Cay. I haven’t seen it elsewhere on Abaco.

A BUNCH OF FLOWERS (the most recent)
FLOWERING ON ABACO (an expedition with Ricky Johnson)
I’ve been planning a post about this lovely small butterfly for some time. I posted a close-up photo of one taken last summer at ATLALA PICS (worth clicking to enlarge to see its cute curly tongue) but I wanted to find out more about them and their strikingly-coloured abdomens. This led me to the excellent butterfly (& co) website of STEPHANIE SANCHEZ. Click her name to be transported to her intriguingly and Greekly named HEURISTRON pages for a wealth of Florida-based lepidoptera information. With Steph’s kind approval, the following post is based on her Atala work, and includes her amazing images of the life cycle of the Atala with captions. The blue links below will take you to the relevant pages of Steph’s site, where you will find plenty of advice about Atala-friendly plants.
THE STAGES FROM EGG TO BUTTERFLY
LARVAE Red caterpillars with yellow markings, hatch from the eggs and eat the host plant. They shed their skin several times while they’re growing up. (You can look up “larval instar” if you want to get more technical than that.)
CHRYSALIS The caterpillars eat, and grow, and then they hang from the bottom of a leaf on the Coontie, shed their skin one last time, and turn into a chrysalis.
BUTTERFLY Inside the chrysalis, the caterpillar turns into the butterfly. When it’s done, it crawls out and hangs upside-down to extend and dry its wings before it flies away.
Up close, the white rounded eggs have tiny hairs on them
COONTIE (Zamia floridana or pumila)
The eggs hatch into these bright red and yellow caterpillars
When the caterpillars have eaten and grown enough, they hang under the leaf, shed their skin a final time, and turn into a chrysalis. The one below is undergoing the change; you can see how different it looks from the bright red caterpillars
On a very new chrysalis the yellow dots on the back of the caterpillar are still visible
Then as it ages, the chrysalis darkens to a more opaque soft brown that darkens more the older it gets
Finally, a day or so before the butterfly is ready to emerge, you can start to see the red abdomen through the bottom of the chrysalis
The little spiky brown splotches near the chrysalides are the shed skins of the larvae
When they first crawl out of their chrysalis, their abdomen is swollen with fluid and their wings are squished and tiny. They hang upside-down and excrete fluid, and also pump fluid into their wings to expand them
This is a good time to hold them; they can’t fly away. Be sure to let them hang upside-down though, or their wings will dry wrong and they will be unable to fly. Also watch out for the goo they poo because it can stain your clothes
All of these Atala Photographs were taken in Broward County, Florida by ©Stephanie Sanchez
WHY THE BRIGHT RED ABDOMEN? I suppose it’s obvious that this is one of nature’s warning signals. But are these insects inherently toxic, or are the toxins acquired by ingestion or some other process? Lifting wholesale from Wiki, which puts it as well as I could (+ useful links), “The host plants contains toxic chemicals, known as cycasins, and the bright coloration of the adult is believed to be aposematic. Birds and lizards attempt to prey on the adults, but find them distasteful and learn to avoid the brightly patterned butterflies.”
Steph advises “if you want Atala Butterflies in your butterfly garden, you’ll need at least a dozen Coontie plants to keep a colony alive; more is better. They tend to stay close to home, so they’re a fun butterfly to garden for because you can continue to enjoy watching them in your garden after they become butterflies. Some other butterflies tend to emerge and fly off.”

“SO THIS IS CHRISTMAS…” Image: ©RH
Christmas time. Holidays. Festive season. Yuletide. ġéohol*. Noel. Winterval. However you describe it, there’s a reassuring ritual each year. To many, the familiar religious carols and rites. To all, the cheerful sound of jingling tills. The exchange of presents happily bought and excitedly received. The groaning table weighted with victuals. Light and laughter. Glasses generously filled and refilled. Sudden growing dizziness and a strange lack of coordination. Wondering what others are saying. Wondering what you are saying. Drowsiness. Overwhelming sleepiness. The passage of time. The groaning hangover as seven West Indian woodpeckers attack your skull with hammer-drills… Time for a soothing image.
Where was I? Oh yes. This is a very good time to draw attention to the various wildlife organisations based on Abaco and in the wider Bahamas. During the year they look after the birds, the marine mammals and so forth that help make Abaco such a very special place to be. I am simply going take the opportunity to post the link to my updated page for ABACO WILDLIFE CHARITIES. Oh. I just have. Well, is there one that appeals to you, I wonder? Just asking… Meanwhile, here’s the music of the heading to get you in the mood
* Old English / Anglo-Saxon origin of “Yule”
Back safely in Blighty at last, and 17 cups of coffee down the line it’s time to take caffeine-trembling hands to the computer. A quick skim through the new batch of Abaco wildlife photos has shown that at least 3 out of (say) 987 have came out adequately, so new material will now be appearing – parrots and other birds, reef fish, plants, bonefishing, and a lot more (including some videos). I’ll make a start with an Atala Hairstreak, a small but unmistakable butterfly that is a creature of delicacy and beauty. It is the one that features in the RH logo above. Here is a live specimen taken deep in the pine forest a few days ago at the Blue Hole known as Sawmill Sink. The colouring is just as it is in real life – there’s been no ‘work’ done on this image. Its little curly tongue shows that it is busy feeding. Click on it to enlarge it.
HUMMINGBIRD MOTHS Hemaris Thysbe
Apart from the plentiful bird species to found all around the Delphi Club, there’s the strange half-way house between insect and bird that is the HUMMINGBIRD MOTH Hemaris Thysbe, also known as Hummingbird Clearwings. These can be seen – and heard – especially at dusk hovering around the flowers in the garden, sipping nectar. In the half-light they are sometimes confused for tiny birds. I have seen them most clearly when they are busy among the flowers in the beds on either side of the lit main staircase. So far I have not managed to get a reasonable photo of one – a situation I hope to put right in May. Meanwhile, I have found some wonderful pictures, not from Abaco, on a website related to a Research Program at Miami University . They were taken by Dr Hays Cummins, to whom thanks for use permission. These and other outstanding images can be found at his comprehensive website, for which CLICK===>>> HERE
ABACO NATURE TOURS with Ricky Johnson
Reluctant as I am to give Ricky even more publicity that he gets already – including passim in this blog – his Nature Tours are seriously good, and his knowledge and enthusiasm for the flora, fauna, geology and history of Abaco are unrivalled. If you want to see a parrot close-up, understand a blue hole or learn which trees and shrubs are poisonous (and which are the antidotes) he is undoubtedly your man. He will even show you birds where you have completely failed to see any & believe there are none

THE DELPHI CLUB DRIVE CIRCUIT
This very pleasant walk somehow seems more satisfactory taken clockwise, turning left at the front gateway and wandering along the guest drive. The straight service drive is less interesting and feels less ‘in the coppice’. The distance is about 2 miles. You can walk the circuit briskly in about half an hour. The birds will see you, but you won’t see them… So preferably take it easy. Here is a fantastic aerial view of the drives (courtesy of DCB)
From a birding point of view, as you walk down to the gateway, keep an eye out on both sides. There are plenty of birds in the bushes and trees, though they are not always easy to see. You might see a western spindalis, bananaquits, black-faced grassquits, warblers, northern parulas, loggerhead kingbirds, vireos, cuban emerald hummingbirds or a bahama woodstar if you are lucky, amongst many others. When you get to the main drives, have a look straight ahead into the coppice – in fact anywhere along the guest drive is worth pausing to investigate.
The gumbo limbo trees are very popular with many birds, including the Abaco Parrots, so it’s good to check them out as you pass by (and if you have unfortunately touched a poison-wood tree, they provide the antidote – conveniently the two trees tend to grow next to each other). Here are a couple of Thick-billed Vireos proving the point. And their song, which you will hear a lot around the Club itself. (credit Xeno-canto.org)
Hairy Woodpeckers seem to favour dead trees for drilling practice – and perhaps for feeding on the sort of bugs attracted to dead wood. Here’s what they sound like (a call and response with 2 birds) (credit Xeno-canto.org)
If you look at the base of the trees in certain places, especially on the the left hand side of the guest drive (facing the highway), there are some small but deep holes in the limestone. If you drop a stone in, you can hear it splash in water – and the ferns growing inside them suggest a continuously moist environment.
As you progress, you move from the hardwood coppice to the pine forest.This photograph was taken just as the forest fires in March were petering out. The theory was that the fires that raged through the pine forest would stop where the coppice began, and not sweep on to engulf Delphi… and so this photo shows. The thick pine forest with its flammable vegetation and undergrowth gives way here to damper and less combustible coppice-wood which has halted the progress of the flames. The pines you can see are the last few outliers of the pine forest.
When you reach the top of the guest drive it is worth carrying on to the highway. For a start you can admire Sandy’s gardening effort on the south side of the ‘white rock’, and maybe do some weeding. You are quite likely to see Turkey Vultures on the telegraph posts and wires, as here. You may also see Bahama Swallows on the wires, and perhaps an American Kestrel on a post.
Smooth-Billed Ani (wiki-ani)
I have seen a raucous flock of Smooth-billed Anis in this area, but it is hard to get close to them. Listen out for this unmistakable noise (credit Xeno-canto.org)
Returning from the road to the fork, to your right is the way you have come – seen here as the fires burnt out. There had been thick, indeed impenetrable, bright green undergrowth all along only 3 or 4 days earlier.
Because this route is more open, there seem to be fewer birds. Again, you may see kestrels on the posts. Halfway along we heard the loud and very melodious singing of a Northern Mockingbird some distance away. CLICK on image (as you can with all, or most, of these photos) and you can see it singing!CLICK BUTTON to hear song of a Northern Mockingbird (credit http://www.bird-friends.com)
It is also worth looking out on either drive for epiphytes, or air-plants, growing on their host trees. They are so-called because unlike say, mistletoe, they are non-parasitic and do not feed off their hosts.
RJ’s eco-tour is not just about parrots and other avians. He is also an expert in the plant and tree life, and a great deal else. Here are some of the flower / tree images from the day, to which I will (may?) put names in due course. But frankly the pictures are far more satisfying than the knowledge that something is or is not a variant of a Cuban Popcata Petal Tree. Or whatever. If you feel like it, fast forward to the end of this post for a blue hole, a butterfly and a team photo…
Having left the parrots and the very lovely private garden we were shown round (where most of the plant shots were taken), Ricky took us to a blue hole nearby. The choice of 3 was narrowed down by the forest fires raging in the area (see FOREST FIRE post. The 2 largest were in a part of the pine forest that was busily engulfed in flame and dark smoke. So we went to the smallest.
However, what we could see was merely the entrance to a large and deep cave system in the limestone rock, the extent of which is still being explored (though not by me, thank heavens). The rock to the left was actually covered by 6 inches of water so clear that you could not see it – as one of our group discovered when he stepped onto the rock…
It was here that we saw ATALA HAIRSTREAK butterflies. This one is a different one from the one in the main BUTTERFLY post… but even their mothers can’t tell
And so to the final photo of the day, taken as we sustained ourselves… before having to leave rather sharpish when the wind changed direction and the smoke and fire decided we might be worth incinerating. Possibly Ricky, in the background on his cellphone, is calling for help…
I have returned from “The Other Delphi” to find that Peter Wesley Brown has provided 3 excellent images, now uploaded to the CONTRIBUTIONS / PHOTOGRAPHS page. Two are excellent pictures of a Gold Rim / Polydamas Swallowtail, dramatically… no, badly photographed by me for the BUTTERFLIES post and later identified by PM; the third shows that THE RELUCTANT WOODPECKER has finally made herself / himself at home in the nesting box…
The (badly-photographed) dark butterfly in the earlier post has been identified as a GOLD RIM SWALLOWTAIL / POLYDAMAS SWALLOWTAIL (Battus Polydamas Lucaeus) Continue reading

Seen all round Delphi this March. These are on the move the whole time, and are surprisingly hard to pin down (not a very sensitive way to put it for a butterfly…) The bottom photo looks like a rubbish picture, I know, but in fact the butterfly is at rest (the body / legs / feelers aren’t blurred) while the wings beat fast and constantly while it feeds
AND FINALLY… Pride of place goes to this Atala Hairstreak, photographed during a Delphi outing with Ricky Johnson to one of the Blue Holes in the pine forest. It’s the only place I have seen these small butterflies, and there were only four or five. This one stayed still for just long enough
