Cyphoderus! - Cyphoderus similis

Cyphoderus! - Cyphoderus similis
Richmond Hill, York Region, Ontario, Canada
April 29, 2007
Size: ~ 1 mm
There is a rock in my backyard which usually has an ant colony beneath it, and I often lifted this rock to find a group of these ants along with some tiny white springtails. I have long wondered what these springtails are and decided to determine that today. I was in for a surprise when I captured some of them!
So here's a C. similis data point for Ontario. They were found in association with what I believe are Pavement Ants (Tetramorium caespitum).

FYI, Cyphoderus similis is the only nearctic member of the family Cyphoderidae. In Europe we have Cyphoderus albinus as most common cyphoderid. It seems this species is not ant species specific. It was found recently that it adopted a new ant species in Belgium / the Netherlands that is invading Europe from south to north.

Yes, I was actually wondering about this springtail's preferences for host ant species. Thank you for the interesting info!

Exciting stuff
