springtail - Hydroisotoma schaefferi

springtail - Hydroisotoma schaefferi
Groton, Middlesex County, Massachusetts, USA
February 9, 2008
Size: 2.5-3mm
Found out on the snow.

Moved
Moved from Desoria.

Hydroisotoma schaefferi
I changed my mind... The olive green colour and cover of short smooth setae excludes Desoria... Agrenia or Hydroisotoma is more like it.
Since you have found H. schaefferi from the same location in the past, I vote for H. schaefferi.

 
Hydroisotoma schaefferi?
I found this on the snow one along the driveway bordered by woods, and not on or near water like most of the H. schaefferi I've found. It's bigger, and the legs are the same color as the body instead of yellowish.

 
I see.
Try to find some specimens and this time take a shot with a dark background. Then we can see the distribution of the macrosetae on the body.

I'm glad you're here to identify the springtails. I had the right family, but the wrong genus.

Not Isotoma...
given the abscence of macrochaetae on the body segments.
The abscence of macrochaetae at the terminal body segments also rule out Isotomurus.
For the time being: Desoria sp.
