Baetis

Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

Some characteristics from the microscope images for the tentative species id: The postero-lateral projections are found only on segment 9, not segment 8. Based on the key in Jacobus et al. (2014), it appears to key to Neoleptophlebia adoptiva or Neoleptophlebia heteronea, same as this specimen with pretty different abdominal markings. However, distinguishing between those calls for comparing the lengths of the second and third segment of the labial palp, and this one (like the other one) only seems to have two segments. So I'm stuck on them both. It's likely that the fact that they're immature nymphs stymies identification in some important way.
27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Hey! I just received in the mail a brochure from the Xerces Society?? I thought maybe Gonzo et al may know something about it. They are looking for money and claim that they are interested in, "Protecting wildlife through the conservation of invertebrates and their habitat". Does anyone know anything about them?

I was told once about a conversation between someone from the Anglers of the Au Sable and a Michigan DNR rep and he had made a comment that went something like this, "We can't manage for invertebrates!"...I guess there is no political "glamor" with the general public in regards to bugs...But we all know that the bugs we watch and imitate are like canaries in a mine and once they are gone we are in serious trouble and our fresh water is in jeopardy.

Here in Michigan the Huron River Watershed Committee watches over the Huron river. It runs through Ann Arbor and ends up downriver from Detroit in Lake Erie. A couple times a year they have volunteers wade the river and collect invertebrates and are especially looking for the lowly Stonefly. It is the canary in the mine and as we know doesn't tolerate compromised water very well.

After the bugs are collected there is a party and entomologists from U of M discuss the results and discribe the critters found. Sounds like fun, eh?! Especially to us bug nerds!

Anyway! Just curious if anyone has any knowledge about this group...The Xerces Society?

Hi Spence-

Yes, The Xerces Society is very legitimate. They are based in Oregon, and do exactly what they claim to do. Some years ago, I had extensive contact with one of their (then) staff, Jeff Adams, who was instrumental in producing a CD, which contains approximately 5000 identified macro photos of aquatic macroinvertebrates from the Pacific Northwest. Particularly in these tough economic times, they are likely strapped like most everyone else, and in desperate need of some financial support.
Best regards,

I helped lead a workshop for them several years ago. Totally legit and very committed.
