Yellow with dark speckles - Pogonognathellus flavescens

Yellow with dark speckles - Pogonognathellus flavescens
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.

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. Compare with its close relative P. elongatus, in which the antennae are longer than the body. The body of this specimen / these specimens appear patcht because the scales are removed partially. Given the small (estimated) size, it is a juvenile. P. flavescens is one of the larger Tomoceridae of the USA. It can become 6 mm in body length.

Tomocerus
Hi Jim. Nice shot of the furcula, that gave Collembola their common name of springtails. Note: third antennal segment is very long.
