can be found here: Life stages and biology of three species of Lygaeinae (Hemiptera–Heteroptera: Lygaeoidea: Lygaeidae) Anochrostomus formosus (Blanchard), Lygaeus reclivatus reclivatus (Say), and Oncopeltus sexmaculatus (Stål)

...I've had a look--and I'm still not prepared to make a species call. :)

If you feel confident of the ID, please feel free to move the images to the species page.

this image series matches those previously posted for L. kalmii on BugGuide, but if you don't feel sure about the species, I wouldn't dare to go over your better judgment

...and your judgement is quite likely superior to mine--especially when it comes to Arizona bugs.

After sharing this post with some coworkers, the following exchange ensued:

Eric McDonald: "They may not be different at all. Check out this article using DNA sequences Testing the Validity of the Lygaeus kalmii Complex

Steve Lingafelter: Interesting that they conclude: “Therefore, our data validate the conspecific classification of L. kalmii angustomarginatus and L. kalmii kalmii and suggest that L. reclivatus is not a distinct species.” However, L. reclivatus is the oldest name and must have priority according to the ICZN (reclivatus was described in 1825 compared to kalmii in 1874), therefore, L. kalmii is the one that may not be a distinct species. But I’m not a hemipterist, so just providing this food for thought...
