Tree Cricket nymph - Oecanthus

Size: 5mm?
Since I found it on goldenrod, maybe Oecanthus nigricornis? (I've never seen adult before though...)

It could be
Apparently I have never seen a nigricornis nymph -- even though the first year I raised some from a goldenrod stem - I thought they were O. nigricornis. A gal doing DNA sequencing research on Oecanthinae visited last fall - and we never found any O. nigricornis. Wisconsin is O. forbesi heavy.

Here's a bad photo of one of my current foster TCs - which I believe will be O. forbesi.


NJ doesn't show Forbes' on the maps - but neither was Wisconsin. I think they have been mistaken for years as O. nigricornis.

Your nymph does look darker overall - so I think you are probably right. The only way to know for sure would be to raise it and hope it's a singing male - to record it's song at a given temperature.
