Scudderia fasciata (Pine katydid, Black-striped Katydid)

This katydid kept moving quickly up the sheet so it was dificult to get a good shot of it. The wing with its "long black longitudinal stripe along the top of the tegmina (thickened, leathery front wings), which are elongated and not broadened in the middle" is characteristic of the species. https://mnfi.anr.msu.edu/species/description/12284/Scudderia-fasciata

As far as I have been able to find out this species is not known from Minnesota and was recently added to the special concern list in adjacent Wisconsin. It is also a special concern species in Michigan where it has been reported from Muskegon County in the lower peninsula in 1991.

Excellent work digging up that info, Gary. I was wonder if "special concern" meant invasive or harmful, but it looks to be a case of it being rare. Posted 4 years ago

  I probably should have clarified "special concern". I'm waiting for final confirmation on the id but, using multiple sources, I've looked over all the species of Scudderia in the US and Canada and there doesn't seem to be anything else like it. Posted 4 years ago

A rare species, nice! Have you shared it elsewhere? It might be of interest on BugGuide. Posted 4 years ago

  I've sent emails to entomologists in Wisconsin and Minnesota and am waiting for them to reply. I'm not sure where this species was found in Wisconsin, the map is blank, but it was probably across from Michigan. The last report from Michigan was 1991 but the Wisconsin report might be more recent. In Michigan, at least, the species occurs in white pine and Canda hemlock stands. It has been reported from Connecticut in New Haven County, West Woodstock in Windham County, and Litchfield County so start looking! Posted 4 years ago

      I was pretty thrilled to find this. At first when I saw it I thought "oh, another kaydid" but when I saw the coloration I changed my mind. Didn't see it last night but maybe tonight? Hope you have good luck finding this katydid. They apparently like white pine and hemlock forests.

      It also gives recordings of the calls although they are just a few seconds. Posted 4 years ago

        I'm hoping to get to a coniferous forest this weekend...I'll be looking for this species! Posted 4 years ago
