BUTTERFLIES ON ABACO, BAHAMAS (2) GULF FRITILLARIES

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

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.
