Observation notes: very hot day we went out to find the calif agave skipper, we never go out this early in the year because it's quite warm for mammals, the book's say this it the time to find calif agave skipper. there was so much action i guess we have to suffer the heat more often. Clear sunny hot we got there in the afternoon, to try to miss the worst of the heat. Think this might be the desert black that monroes speak of they show the blue of anise in circle patterns, and the black in more of a solid band drifting down towards tail end of hind wing. Large shrubs with black larva on them also attest to this being a black. turpentine broom will submit those also, anise larva are similar but very different. Butterflies of borrego desert book by the monroe's is perfect field guide for the area. we saw c, patch c. giant skipper, tiny checker spot. and many more we will post.
