Butterflies from Costa Rica
The main book I'm using for butterfly IDs is Glassberg's Swift Guide to Butterflies of Mexico and Central America, but it has only two-thirds of the Costa Rican species. I'm also using Butterflies, Moths, and Other Invertebrates of Costa Rica by Carrol Henderson, but it's nowhere near comprehensive. So my IDs are very tentative, and confirmation or correction is welcome.
