narrow, grey springtail - Entomobrya confusa

narrow, grey springtail - Entomobrya confusa
hUDSON, Hillsborough County, New Hampshire, USA
October 31, 2006
Size: about 1.7 mm
Found under bark of small mostly-dead tree along with at least two other springtail species.

Moved from Entomobryidae.

Entomobrya confusa
Hi Jim. This species has a uniform background colour usually with darkened posterior margins of the thoracic and first 3 abdominal segments. Might be confused (pun intended) with E. sinelloides in which ALL abdominal segments have a dark posterior margin.
Compare with the picture of E. sinelloides made by Tom.

Thank you, Frans.


Hi Jim. Note the very long fourth abdominal segment, typical for Entomobryidae. BTW, in Entomobryomorpha, the first thoracic segment cannot be seen from dorsal view. Therefore, start counting abdominal segments from the narrow third visible segment.

Thanks, Frans.
I am very ignorant about these creatures, so I appreciate the ID pointers.
