Hudson, Hillsborough County, New Hampshire, USA

Size: about 2 mm
Photographically this image is on the horrid side but it demonstrates some interesting behavior. This springtail appeared to be looking upward toward my camera lens, perhaps deciding wether it represented threat or opportunity to escape the harsh glare of my light arena. I imagine the forward-tucked antennae helped to give it an unobstructed view. Of course I could be misinterpreting the action.

Tasting behaviour
Hi Jim, Collembola have a quite elaborated organ at the tip of their antennae (several specialised setae, called sensilla, placed near to the tip and some have on top of that a kind of exposable and retractable bulb at the tip). This organ can be compared with our taste organ.
So, I guess, the specimen is figuring out whether or not the stuff beneath its feet is consumable or not.
It is a nice shot of such 'tasting behaviour'. Good of you to notice that.

 
I suppose you're right, Frans.
Good of you to comment :-)
