Bear-Bodied Springtail (Morulina multatuberculata) - Neanura magna Bear-Bodied Springtail (Morulina multatuberculata) - Neanura magna

Moved

Neanura magna
Although the specimen resembles Morulina at first sight, it turns out to be Neanura magna. The largest Neanura species in the USA.
It has only 5 dorsally visible abdominal segments. The 6th abdominal segment is completely covered by the 5th. As in Morulina...
Note the 'reduced' middorsal tubercles (not reduced in Morulina).
Note also the typical 'triangular' arrangement of the tubercles on the 4th abdominal segment. In profile it looks as if the segment bears 2 tubercles, one closely behind the other.
