What
Pale Dun (Ephemerella dorothea)Observer
jerry2000Description
Small, yellow body, light grey wings, 3 tails.
Apart from the insects, I heard some of the quacking-type katydids (or cicadas?) that have ben around of late. These were heard where I was fishing, and also back at the car by route 9. Also heard the buzzing type of katydids/cicadas? by route 9. Did not hear the whippoorwill, which in recent weeks had been calling a lot near dark at this location.
Ate a few blueberries on the way to the stream. These are about done - there'd been a pretty decent crop 2-3 weeks ago.

What
Holarctic Alderflies (Genus Sialis)Observer
jerry2000Description
Several specimens 10 mm in length, one specimen 15 mm long (body only). I had thought these were caddis, but my more knowledgeable friends assured me these are alderflies. The different sizes are different genders - females likely the larger ones. Similar markings: dark brown/black body, with dark orange showing in abdomen segments and on side of abdomen. Heavily veined wings. The smaller ones seem to have a darker, almost all-black head, whereas the larger one has some dark orange about the head and "neck".
