Pelham, Massachusetts, USA

Size: 1mm
Found in a puddle created by the melting snow on my walkway. I recall seeing them here in previous years but this is the first time I thought to get some picks. Is it all the same species? I see a lone dark one and some white ones. Different species?

Springtail? Springtail? - Ceratophysella Springtail? Springtail?

Hypogastruridae : Ceratophysella mass aggregation
4 species are involved:
1. the large pink one = Ceratophysella sp. making out most of the aggregation.
2. the tiny globular one = Sminthurinus sp.
3. the blue one = Hypogastrura sp.
4. the white one = ?

festival of color
Beautiful critters! The pink ones look like they could be in the family Hypogastruridae, and the tiny, globular orange guys are some kind of Symphypleona.

So two different species? Why
So two different species? Why are they together? What about the lone black one and the white ones? Also different species? Is it possible to get the exact species of the orange and red ones? Thanks so much!
