Yellow with dark speckles - Pogonognathellus

Yellow with dark speckles - Pogonognathellus
Hudson, Hillsborough County, New Hampshire, USA
November 1, 2006
Size: 3 mm or so
Did not measure.

In all, I did a very poor job with this batch of springtails (1, 2, 3, 4, 5, 6) I found near a marsh on a small log partially covered (esp. on bottom) with a layer of dry, brown fungus. For some reason they all died soon after placement in my light arena despite frequent mistings to prevent dehydration. Then, while photographing their tiny corpses I seem to have forgotten to shoot any next to a millimeter rule. Finally, I cannot atest that any of these photos are of the same individual, so I will probably unlink them after posting them with the same set of data.


Moved from Tomoceridae.


Not Tomocerus pogonognathellus...
But Pogonognathellus flavescens.

Moved from Tomocerus.

Pogonognathellus flavescens
Hi Jim. P. flavescens is normally uniformily leadgrey, silvergrey when all scales are intact. If the scales are removed, the body colour is uniformily yellow, however. Hence, its name 'flavescens'. Another characteristic: its antennae are shorter then its body.
This is a juvenile specimen. Adult P. flavescens are between 4 to 6 mm.


This dead specimen is shrunk to such an extent that it at first glance resembles Lepidocyrtus... But the long antennae and long abd.III reveals it is Tomocerus.
