When you get a moment, check out Jim's sites; they're impressive.<br /><br />Awesome, Jim. Thank you very much. I wonder which species is more common.

You may have to be content with calling them <i>annexum</i>/<i>boreale</i> until you look at one in-hand.<br /><br />JimAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-8210757346121712556.post-66167618937247545602011-07-19T22:30:25.445-07:002011-07-19T22:30:25.445-07:00Well, that's made my day!

We tend to rely on several cues:<br /><br />1. The pattern on segment 2 of the abdomen.<br />2. The amount of blue on segments 8, 9 and 10 of the abdomen.<br />3. Thorax markings (width of stripes).<br /><br />Additionally, 2 species have red eyes and 1 species has white legs.<br /><br />I am not familiar with any of the species you mentioned, but sympathise greatly with your predicament.
