Finally rain! Which of course produces bad photos
We have water again in our streams. Unfortunately, the rain was so heavy -- at our house, I measured 3.5" -- that it muddied up a lot of the water. And, that can lead to photos like the one at the top of the page. (Lots of silt on the head and pronotum: on the case as well.)
Back to Sugar Hollow this morning to a small stream just to the west of the stream that I went to last week (10/9), not at all far away. And last week, you'll recall, I found these beautiful, "clean," Goeras (weighted-case makers).
The heads and pronota are easy to see. Not so when the larva is covered with silt.
Ah well...at least I'm pretty sure now that Goeras inhabit most -- if not all -- of these small streams I explore.
Species? Again G. calcarata. No sign of sternal plates (see the post of the 10th); and three pairs of sclerites on the metanotum.
I didn't see many insects today -- other than two Goeras. There was a fair number of common stoneflies in the leafpacks (leaves are building up and decomposing) -- Acroneuria abnormis and Eccoptura xanthenses. I was hoping to see the first Perlodid stones of the season: maybe next time.
