Nannothemis and I are attending the AOU conference in Portland, OR. We are managing some time to look for insects, but with limited success.
Yesterday, we visited the Portland Audubon office/store in Forest Park. This park is the largest urban forest reserve in the US. The sanctuary near the Audubon facilities includes a pond next to Balch Creek.
We were immediately treate with a couple of male Cardinal Meadowhawks (Sympetrum illotum) fighting over their small territories.
Here's one obelisking.
We also saw several Pacific Forktails (Ischnura cervula).
Here are a couple photos of males.
...and a female
We also saw one or two darners patrolling the pond, but we never could get a decent look for an ID.
Tomorrow we should have time to check an area or two near the Columbia River. Hopefully, we'll find more species.
