BEES & WASPS
Gray Velvet-ant (aka Thistledown Velvet-ant), Dasymutilla gloriosa, MUTILLIDAE FAMILY: It looks like a hairy ant, but it is a wasp. The sting of the female is said to be very painful. The velvet-ant pictured (September 2012 photos) kept rotating its rear end to face me while I was trying to get a shot of it from the front. I tried to trick it by straddling over it and angling my camera.

Painted Stink Bug, Bagrata hilaris, TRUE BUG ORDER: First detected in Orange County in 2008, these bugs originated from either Africa or Europe. They are found more often scurrying across the trail than in plants. One time I watched a mating pair, with the larger bug communing with a group of nymphs that were gathered around a spot on the sand - perhaps a spot of moisture?

SPIDERS
Green Lynx Spider, Peucetia viridans, OXYOPIDAE FAMILY: These spiders are so beautiful, especially when they are backlit by the sun and you can see how translucent their cephalothorax and legs are.

Spotted Milkweed Bug (aka Large Milkweed Bug), Oncopeltus fasciatus, LYGAEIDAE FAMILY. Their coloring ranges from red to orange with black segmented antennae, legs, and scutellum (rear shield). The red bugs are the older bugs (Milne, 479). Spotted milkweed bugs hibernate, but will come out on warm days (Essig, 347).

Three-legged Bug (not to be confused with the pest-like Indian walking stick), Emesaya brevipennis, REDUVIIDAE FAMILY: I thought this was a spider at first, but then I noticed how it held its two front legs in front like a praying mantis. Rather than being caught in the spider web, it was slowly picking its way across the web like a tightrope walker. Later I read this bug likes to prey on spiders and to rob them of their prey. The two smaller spiders I saw that were attracted by the walker probably became its meal.
