These two species are found in Mill Creek (tributary to the Russia River, near Healdsburg, CA). There are both a panel case and a turret case. Panel case is the first one shown. These insects are found in leafpacks for the panel case and grazing diatoms for the turret case.

Mark. Great pictures as always...I'm beginning to think that there may be a book hiding in here somewhere and we are all getting a preview. :)

Millcreek - I like the cases going from turret to rocks and rocks to panels. These are great examples of the variability in case style with populations and between instars. Do you see any setal or other color differences (beside the legs) between the two species? Are you collecting the same locality on Mill Creek all the time or are there major altitudinal/vegetational differences in these collections?

Creno - These were collected in the same area of Mill Creek (the same 100 yards). They are separated in time though, with the turret cases coming first in July and grazing on diatoms, and with the panel cases showing up around September and grazing on leaves. I haven't noticed any setal differences between the two although there may be some.

MiltRPowell - Thanks very much for the kind words.
