D. minuta

I was pretty certain that this would be D. ornata.
Thanks, Frans.

Moved from Springtails and allies.

The difference between D. ornata and D. minuta :

In D. minuta, only the black posterior abdominal patch is distinct.
In D. ornata, in addition to that black patch, there is a very distinct and complex pattern of dark pigmentation on the abdomen.

Early and pale instars of D. ornata may look like D. minuta.
If this small specimen is from the same habitat and population as the other D. ornata you have uploaded, it will be more probably a juvenile D. ornata, as you said.

I leave it up to you to decide.

D. ornata or D. minuta

This one was at the exact place (same pail) that the frozen to the ice D. ornatas from this spring were found. The recent D. ornata was about 30 feet away.
Should I leave it at the Genus level?

Thanks,Frans, for the explanation.

Dicyrtomina minuta?

Given you have found this specimen 30 feet away from the other D. ornata we cannot say it belongs to the same population. I would suggest to sample the same location for about 2 weeks. If you find any adult D. ornata within that period of time I would idy the specimen as a juvenile D. ornata. If you find any adult D. minuta within that period of time, classify it as a juvenile D. minuta. If you find no adults, keep it at genus level.

Thanks, Frans

I have much better luck finding these here in the cooler weather. which is nice since other things are diminishing for winter.
