An experiment...how many different interesting insects and arachnids can I find in less than a half an hour in an area I can reach without taking a step.
The answer is dozens. But here are a few highlights.
A tiny little wasp of the genus Ammophila. Your guess is as good as mine on the species, there are a thousand of them. Obviously a female from the ovipositor.
This little dude is about 3/8 of an inch long. A fly, not a bee, and from the subfamily Eristalinae, which are flies that imitate bees for protection from predation. Pretty cool. Again, genus and species are anyone's guess. My guess is an E. flavipes. Probably wrong.
There are a few others, of course, but there needs to remain some mystery in life.
