Elongate Springtail - Pogonognathellus dubius

Elongate Springtail - Pogonognathellus dubius
Near Ruraldale, Upshur County, West Virginia, USA
November 6, 2006
Size: 4.0 mm
I was photographing flies at a Sugar Maple seep on a warm November day when I saw this fast-moving fellow. I got a quick photo before he was lost in the crevices of the bark at the base of the tree.

Tomoceridae or Entomobryidae, perhaps?

Moved from Tomocerus.

Pogonognathellus dubius
Hi Stephen. Based on the fact that its antennae are as long as its body.


Hi Stephen. Tomoceridae indeed. The typical characters is easily recognised: long antennae, with 3rd antennal segment very long and thus longest.

Thanks very much, Frans! I really appreciate your help with this interesting springtail.
