Stink Bug

Stink Bug

6181  Hello,  Trying to figure out what came in on my Christmas tree. We are in Calgary, AB area and the store tells me the tree came from out East- likely Quebec or NB. The tree was outside for several days, but it has been a very mild winter ( typically above freezing days).  Cheers,  Tanya

This is a stink bug (Hemiptera/Heteroptera: Pentatomidae) in the genus Chlorochroa, possibly C. ligata, a species widespread in Canada; see https://tinyurl.com/ydcsywmr for some images. This species appears to feed primarily on developing seeds, especially those of plants in the legume family. It does not appear to be a serious pest species in Canada, but has been reported to damage cotton bolls in the southern United States where it is known as the conchuela stink bug.
