When in WA insect collecting, I used a kick net, home-made with two dowels and window screening material.

No problem; I promise not to make a practice of it.;)

They are classed as semi-aquatic. Here is what Pat McCafferty says about them on pages 366-367 of Aquatic Entomology: NOCTURID MOTHS (Family Nocturidae) LARVAL DIAGNOSIS: (Figs. 18.7, 18.8) These generally measure 30-70 mm when mature. Thoratic legs are well developed. Prolegs are...

Yes Mark, that's what I was initially thinking as well. However, after spotting the fully developed head on the middle specimen, and the functional thoracic legs on the leftmost specimen, in Paul's top photo, I ruled out cranefly larva.

Hi Paul_- I believe them to be Nocturid Moth larvae, perhaps (but not necessarily) Yellow Water Lily Borers (Bellura gortynoides).

Yes, I've noticed.

Whatever

Yes, the bulbous abdomen is what led me there as well. Thanks for sharing. :)

Yes, it sure is. :) Would you like to share the clues that led you there?

Larva yes, but not a Cranefly larva.

Great job, Mark. ;)

I assume you are referring to an Aquatic Sowbug. However, I believe it to be a Water Penny Beetle larva, probably of family Psephenidae, subfamily Ebriinae.

Hi Squamishpoacher- I believe this caddisfly adult to be a Little Sister Sedge (genus Cheumatopsyche).

Hi troutpocket- I believe it to be an Ichneumonid Wasp.

Okay, now I understand what you meant. "Small Minnow Mayfly" is the common name assigned by taxonomists to mayfly family Baetidae, and "Armored Mayfly" is the common name assigned by taxonomists to mayfly family Baetiscidae. Whereas, flyfishers have generally been responsible for the common...

Customarily, Caenis emerge (pretty much all at once) around dusk.

Well, that closely corresponds to my experience with a Caenis emergence. In your photos, I assume all but those with obvious wings are subimaginal exuviae. Is that correct?
