Little Glassywing
The weather was hot, 89º F with s slight breeze and intermittent clouds. About 90% of the milkweed encountered was in full bloom. There were fewer plants than in prior years at this location, but all of them looked very healthy and robust. There was a good variety of species, but very few individuals of any given species were seen. The trip was from 1:30 to 3:30 pm. One of the highlights was seeing two Monarch caterpillars near the entrance only a few minutes into the trip.
