SWALLOWTAIL BUTTERFLIES ON ABACO


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.

DRYAS JULIA (JULIA HELICONIAN): BUTTERFLIES ON ABACO (4)

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.

BUTTERFLIES ON ABACO (3): COMMON BUCKEYE

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…

As it feeds, or as the sun warms its wings, the buckeye will start to reveal itself DSC_7831DSC_7825DSC_7817 DSC_7823

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.DSC_7829DSC_7822DSC_7830DSC_7832

The GULF FRITILLARY Agraulis vanillae is a so-called ‘longwing’ butterfly species found from South America to central North America, named for its migration route over the Gulf of Mexico.Gulf Fritillary Abaco CSK 7Gulf Fritillary Abaco CSK 2

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.Gulf Fritillary Abaco CSK 6

FLUTTER BY, BUTTERFLY: ATALA ENCHANTING ON ABACO

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.

This close-up in particular shows clearly that the vivid blue markings are not confined to the Atala’s wings. They are also on the body, the head, and surprisingly on the legs as well.Atala Hairstreak Butterfly, Abaco 6

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.Atala Hairstreak Butterfly, Abaco 3

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

Finally, you may want to get a sense of size for this butterfly – crops and zooms can sometimes give a distorted impression. So here is a normal snap of the butterfly feeding.Atala Hairstreak, Abaco 9

THE LIFE CYCLE OF THE ATALA HAIRSTREAK BUTTERFLY (Eumaeus atala)

THE LIFE CYCLE OF THE ATALA BUTTERFLY Eumaeus atala

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

Atala Butterfly lays eggs on Coontie

 EGGS are laid on COONTIE the Atala Butterfly HOST PLANT (clusters of 10 – 50)

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

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

Atala butterfly chrysalides

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 chrysalisAtala butterfly chrysalides

 The little spiky brown splotches near the chrysalides are the shed skins of the larvaeAtala butterfly chrysalis

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

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.”

ATALA HAIRSTREAK – ABACO’S LOVELIEST BUTTERFLY


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.
