Orange butterflies are some of my favorite around the yard. Maybe because they contrast so well with all the green. I've seen these for years and don't remember ever looking the names of them up. You're in luck, I happen to have a butterfly guide sitting on my desk today.
Scarce Silver-spotted Flambeau
Long tailed skipper
Not sure about the one below.
Pink Cattleheart, hard to shoot these buggers! They're fast and do not stop. Ever.
Each year the hummingbird moth shows up in the garden at the start of rainy season. He's been around a little over a month this year and try as I might getting a decent shot has been next to impossible. Not because they fly away, they are just so damn fast! I did manage to get a few good shots the other day.
