Springtails - Hypogastrura harveyi

Springtails - Hypogastrura harveyi
Elkins Park, Montgomery County, Pennsylvania, USA
February 9, 2010
Size: 1-2mm aprox.
Strange larva: we found these today all over a snow bank. There were dozens of them climbing around in the snow. VERY tiny, only 1mm - 2mm and, because they were so dark against a pure white background, extremely difficult to photograph even with my nice macro lens. Also, like fleas, when disturbed they could jump a fair distance. Any idea what these could possibly be?

You beat me to it!

Hypogastrura harveyi
given the antennae are longer than the head.
One of the more common 'snow fleas'.

Frans, I'd be honored to have my images at your site as long as, as you say, all copyright info stays intact. I personally didn't think the images were of all that good a quality, given the shooting conditions, but I'm glad you like them enough to wish to use them for your .org.
And thank you for the positive ID!

for your kind permission.

Snow fleas
The common winter springtails on snow are the "snow fleas" of genus Hypogastrura(1).

Moved from ID Request.

Wow, I thought they were larva! I was comparing their body to ladybug larva because I thought it looked similar...shows you what I know!
Thanks for the ID! I was just reading the info on them and it's amazing I never noticed them before!
