Hi Siam, I'm so happy for your success with rearing all the butterfly cats to adulthood. What a lovely butterfly too. I would love to ask you if you'd show more photos of your butterfly/cat rearing container, and give instructions as to how you use it? I am going to try and rear some myself this year, and your setup looks so professional. I'd really appreciate your help and knowledge. TY :)

Was it eating it or just resting? Sometimes they go off the host plant to rest and molt. Many predators are searching host plants for caterpillars. I saw a book listed for "Butterflies of Trinidad and Tobago", but there are only out of print copies and they are expensive. Do you have a library? Maybe you could check out some field guides there about butterflies. In North American, the caterpillars eat: "Habitat tropical to Transition Zone woodland and Citrus groves. Ranges south to Colombia, Bimini, and Cuba. Hostplants tree and herb Rutaceae: Citrus sinensis, limon, aurantium, grandis (?), Zanthoxylum fagara, americanum, clava-herculis, hirsutum, Ptelea trifoliata, Ruta graveolens, Casimiroa edulis, Dictamnus albus, Amyris elemifera, Choisya; Piperaceae: four spp. of Piper in Cuba. R. Sim observed eggs laid on (and larvae eating) Staphyleaceae: Staphylea trifolia. Records of Nyssa sylvatica (Nyssaceae), Persea borbonia (Lauraceae), and Populus (Salicaceae) seem erroneous. Both P. cresphontes and P. zelicaon(6) fed on Citrus in the San Joaquin Valley, Calif., though cresphontes was a stray there and is now eradicated." This is from "The Butterflies of North America, A Natural History and Field Guide" by Dr. James A. Scott. I also searched on the host plant database. You can put in the plant or the butterfly/moth, but you have to use the latin name. Here is a link that might be useful: Host Plant Database for Papilio cresphontes Giant Swallowtail

Common Checkered Skipper, Pyrgus communis. I don't think there is anything "common" about them, and that they are one of the prettiest skippers. Actually, I think it is called "Common" because it is one of the most often seen. I don't see them often in my garden at all, and love it when I do. The milkweed looks like Common Milkweed, or Asclepias syriaca. Could be one of the other broadleaf milkweeds, but since it is more common than other milkweeds, I'm gonna go with that until someone has a better idea. Susan

It's a butterfly. Two things confirm this: the wings are folded up above the head at rest (moths typically do not do this, with some exceptions); and the antennae end in clubs. This individual appears most likely to be an Orange Sulfur or a Clouded Sulfur. Jeff
