Like many others, I've had targets of opportunity flutter by & often had no clue what it was I "shot". Like here:
Most sites I've found are useless! Why? There's NO image index page, so you have to click on every freakin' name to find something you're trying to ID.
Would it be SO hard to provide a page of thumbnails for us? Well, I've found a couple that do have thumbs:
The Detroit B-Fly house gets many of theirs from Costa Rica. Jay Levin has tried to get as many as possible & posted them on Pbase.
Some Residents of the Butterfly Garden at the Detroit Zoo
Butterflies of North America
It would help if the Thumb page had a few thumbs, but you can't have everything!

If anyone has a similar THUMB site, please help us all out & post a link here. It should save you time trying to ID the unknowns we've encountered!
