small scales
San Leandro, Alameda County, California, USA
March 31, 2005
Size: 1mm
These are the smaller scales that were also on the apple tree with these much larger (?)scales. The ants didn't seem to pay any attention to the smaller scales, but I was wondering if they are related to the larger red & black ones.

Sorry about the bad photo quality.

I would say yes.
I think that these are probably the young stage of the larger scales. If you use both the adult and the nymph, you might be able to search and find what kind you have. If you check the adult picture, I believe I posted some potential genus names for your scale - 4 genera of lecanum scales.

Coccidae - Eulecanium?
I did find some images on ScaleNet of Eulecanium kunoense (in family Coccidae) that look exactly like my scales. I looked through all ScaleNet's other Coccidae images, and at images on other web sites and books, and was not able to find anything that matched nearly this well.

Eulecanium kunoense seems to be from China but is found in my area of California too. (The photos on ScaleNet are from my area.)

However, I e-mailed one of the folks at UDSA who maintains the ScaleNet site, and he said they wouldn't be able to ID my scales without my sending specimens--preferably newly matured females. I don't have the appropriate vials and alcohol for this (maybe I should get some so I'm more prepared next time). Also most of the scales on the tree now are "old"--some have died, some are about to hatch their eggs and die, some are younger but I'm not sure if any of them are "newly matured."

I'm still looking for crawlers--would like to photograph them--but haven't seen any yet. I'm sure some of the eggs are hatching while I'm not watching.
