‘ATALA FASCINATING’: THE LIFECYCLE OF THE ATALA HAIRSTREAK ON ABACO

‘ATALA FASCINATING’: THE LIFECYCLE OF THE ATALA HAIRSTREAK ON ABACO

I have posted about several of the wonderful butterfly species the live on Abaco, but my favourite will always be the small but beautiful Atala Hairstreak Eumaeus atala. Its ‘look-at-me’ bright orange abdomen, black wings and the curious luminescent bright blue spots that even cover its legs and head are unmistakeable. These butterflies favour the coontie plant – especially for egg-laying – but they can be seen almost anywhere as far as I can see, though I have never seen one right by a beach.

I’ve posted before about the lifecycle of the Atala, but I have never had a chance to show the complete post-egg process from caterpillar to triumphantly emergent butterfly actually recorded on Abaco until now. Thanks to Rhonda Pearce, her patience and her skill with a camera, the following sequence of photos shows in detail the various stages of metamorphosis.

THINGS TO LOOK OUT FOR

The little hairs on the caterpillars (larvae)
The dark gluey-looking shed skins
The delicate silky threads as the chrysalis forms
The butterfly emerges upside down, enabling it to uncrumple & spread its wings to dry

PS Sorry, I’ve been very po-faced and not mentioned Halloween. Everyone else is covered in blood, guts and gore, so I reckon the market is saturated. Also I get the wrong end of the ‘Trick or Treat’ stick. I carefully prepare 2 lots of choccy-based sweets. One is delicious. The other contains chilli. If the callers are nice, they get the Treat. If not, they get the Trick. That must be right, surely. I can listen to them hawking and barfing as they run off into the night…. [No children were hurt in the making of this story…]

FLUTTER BY, BUTTERFLY: ATALA ENCHANTING ON ABACO

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.

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

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.

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

January 5, 2013 by Rolling Harbour

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

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

Atala butterfly chrysalides

Then as it ages, the chrysalis darkens to a more opaque soft brown that darkens more the older it gets

Atala butterfly chrysalis

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 Atala butterfly chrysalides

The little spiky brown splotches near the chrysalides are the shed skins of the larvae Atala 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

Atala butterfly emerging from chrysalis

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

June 10, 2012 by Rolling Harbour

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.

FLOWERING ON ABACO: EXPLORING WITH RICKY JOHNSON

May 20, 2011 by Rolling Harbour

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…

BOUGAINVILLEA Bougainvillea Spectabilis

SAPODILLA Manilkara zapota

Three images of a STAGHORN FERN Platycerium bifucatum, an epiphyte or ‘air plant’: one that grows upon another plant non-parasitically

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

ATALA HAIRSTREAK

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…

ABACO BUTTERFLIES AT DELPHI / CONTRIBUTIONS / BLOG FORMAT CHANGES

April 21, 2011 by Rolling Harbour

As a change from birds, here are some other flying items, mostly from around Delphi itself, with a redesigned logo in their honour.

JULIA LONGWING Dryas Julia (Delphi Beach – plant now ID’d as a Bay Cedar Suriana maritima, much enjoyed by butterflies and bees)

HAMMOCK SKIPPER Polygonus Leo (Delphi Service Drive)

GULF FRITILLARY Agraulis vanillae (Delphi Guest Drive)

I haven’t nailed the ID of this one yet. Any ideas appreciated. [See later post for ID as GOLD RIM SWALLOWTAIL / POLYDAMUS SWALLOWTAIL (Battus Polydamus Lucaeus) ]
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
