charzard Posted May 19, 2017 Share Posted May 19, 2017 Found this little one outside in Connecticut. In the grass by my house. Adorable! Any idea what kind? Field roach of some sort? Quote Link to comment Share on other sites More sharing options...
All About Arthropods Posted May 19, 2017 Share Posted May 19, 2017 It's a nymph of the largest wood roach species, Parcoblatta pennsylvanica. Quote Link to comment Share on other sites More sharing options...

Nope, for Blaberids the last segment method is sufficient, but for the others sexual dimorphism or wing length is generally used in determining sex (although these are not as accurate as the aforementioned technique).

Hisserdude Posted May 19, 2017 Share Posted May 19, 2017 Going by the size of the thoracic segments, it's a subadult male. Quote Link to comment Share on other sites More sharing options...

So you can also get the gender by looking at the top of the segments? Quote Link to comment Share on other sites More sharing options...

In Parcoblatta, yes, the male nymphs (or at least large male nymphs), have much larger thoracic segments because they have much longer wings as adults, the females' segments look more normal and proportionate to the rest of their body.

Ah.......I need to brush up on my arthropod anatomy, I usually just refer to those as "wing buds". lol 1 Quote Link to comment Share on other sites More sharing options...
