Iridescent Wasps

2:00 p.m. The last of the sunflowers in Pleasant Valley are giving out, and a just a few remain at the natural gas check-value in Pleasant Valley at mile 1.3 across from picnic site 11. I check them for pollinators. One is surrounded by a swarm of about 10 micro wasps. They are less than one-quarter of an inch long and are steely dark blue green. Their thoraxes and heads are iridescent, and their wings are brown-black. They are definitely not flys, as they have discernible stingers. They are not the same micro-wasps seen back on August 9th. Those had yellow banding on their thoraxes while these are completely black. I am unable to identify these wasps, nor have I seen them before in the canyon.

In the canyon on this warm fall afternoon, there are two groups, lead by graduate teaching assistants, of university biology seniors studying plant systematics (University of Utah BIO 5435). They carefully go through each plant along the roadside and discuss its scientific name. These are the real current and future experts on classifying life in the canyon.

Late in the evening, another storm front moves in, and a cold rain falls.
