Springtail_1024 - Tomocerus minor

Springtail_1024 - Tomocerus minor
Brooklyn, Kings County, New York, USA
May 25, 2008
Something in Tomoceridae perhaps? Found in my compost pile with many more (possibly several species). Lots of ants and moth flies were there as well.

Moved from Springtails and allies.

Thank you for both the the ID and tutorial.

Tomocerus minor
Given the cylindrical 3rd antennal segment.
Normally adult T. minor has a uniform bluish iridiscent body colour.
A uniform greyish iridisation is typical for Pogonognathellus flavescens. But this is to be excluded due to iridisation of only the first basal antennal segments.
In Tomocerus the 3rd antennal segment lacks scales. In Pogonognathellus scales are present on the third antennal segment, causing iridisation and reflection effects.

A juvenile specimen probably.

Tomoceridae, indeed.
