Male Perdita on Calochortus - Perdita - male

Male Perdita on Calochortus - Perdita - Male
Circle X Ranch, Santa Monica Mountains Nat. Rec. Area, Ventura County, California, USA
July 7, 2010
Male Perdita perched on flower of Calochortus plummerae, where he was waiting for a female to come around (which eventually happened).

Image (and inset) clearly show a key character of the genus (and the family Andrenidae in general). Namely, the presence of two (rather than one) subantennal sutures for each antenna, coming down more or less vertically from the inner and outer bases of each antenna and meeting the epistomal suture below (that being the "moustache"-like groove separating the clypeus from the upper face).

Other details concerning ID can be found with this post of another male of (presumably) the same species photographed later that afternoon.

You're welcome, Jeanne
Glad you're learning from my posts! I do put a lot of time and effort into researching them and trying to summarize what I've learned in a way that will benefit others who may be interested. Always nice to hear from such "others", and to know of their appreciation :-)
