ID Question
I have one of my own from Nova Scotia like this. Macaria minorata, bicolorata, bisignata, and masquerata all seem to have similar examples. How are they separated? I don't have access to the description for M. masquerata and the original descriptions for the others don't help me much. M. bisignata does look like the best match to me based on BOLD images but M. masquerata in particular looks close.

I'm puzzled
I don't remember ever thinking I knew how to tell the Macaria species apart, so I'm not sure why I moved this to species level.

I'm Shocked!
Shocked to find that you can't remember why you moved Photo#359483 on January 9, 2010.

OK, I'm over it. Let me know if you ever find a way to tell these apart. Thanks!
