Thank you for the ident auntnance 123 ......... answered another ident for me as well.
It is quite likely a Giant Swallowtail as they lay their eggs on Citris and look like Bird Scat as a defense against being eaten!
Nice work auntnance! Great link too, that's quite a transformation from 4th to 5th instar.
We have a similar one here in Costa Rica. It has a bright red forked "tongue" and emits an awfully strong smell when molested. I haven't seen any recently in my citrus trees but I am looking.
It's probably a swallowtail of some kind: the early caterpillars often mimic bird droppings and some are notorius consumers of citrus. This one is particularly cool for the pairs of horns.
Looks like an early instar of a pretty cool caterpillar. What's the underside like?
