I learned that standing on mucky ground, with a pack (full of extra lenses, etc.) and trying to focus on something the thickness of a straight pin, with the zoom cranked out to 300mm and the autofocus insisting there was nothing to focus on--so I had to do it manually, with sweat running into my eyes--rarely leads to the best-quality images. However, some of the them turned out fairly well:
At this time of year, the cow parsley has pretty much gone to seed--and the black swallowtail caterpillars are just getting started on it. This (according to my caterpillar field guide) is the "desert form" of the black swallowtail's caterpillar. [However, today several people told me that it's not, that it's an earlier instar of the regular black swallowtail "cat" because the desert form doesn't go east of Arizona....EM, 5/18/07]
So, not to overload you with images...that's it for the evening. But if you check the galleries, there's some new stuff in butterflies and dragonflies.
