Many Uca pugilator (sand fiddler). I wanted to name them all and make them my army.
Uca pugilator (male)
Borrichia frutescens with what I believe to be Ascia monuste (great southern white) due to the habitat I found it in and the plants it was pollinating.
I used the National Audubon Society Field Guide to Florida to identify the sand fiddler crab and the great southern white butterfly. I love this guide for its glossy, color pictures that help me identify things I'm not specialized to identify.
