Mining Bee   (three photos)
Pseudopanurgus aethiops


Pseudopanurgus aethiops mining bee in Utah

I first noticed this small black bee resting vertically on a stick of grass near some Curlycup Gumweed on Antelope
 Island.  I attempted
to take a photo of it at which time it flew over to the gumweed.  I managed to get a few shots
of it before it grew weary of me following it around and went back to the stick. I stumbled my way back to the
stick only to have the bee return to the gumweed.  It flew off, not to return, after I persisted in trying to get more
 photos. It was hard to leave alone because it was a beautiful bee with very black wings (like many wasps have)
and partly yellow legs.  It also sported a pollen-covered patch of yellow on its cute little face. Photos don't show
black well, but this bee appeared very black - so black that from a distance I thought it could be
  a rove beetle clinging to a stick . Below is a view of it from the top. © Carol Davis 8-27-2015

The article, "Notes on Certain Bees with a Consideration of the Use of the Abdomen in Nest Construction"
by Charles H. Hicks, mentions this little bee, starting with the third
paragraph; however,  it doesn't
contain the full text. That's all I could find out about it except that Bugguide does mention it visits
flowers from
Asteraceae and Chenopodiaceae families.  Curlycup Gumweed (Grindelia squarrosa), like
sunflowers, is from the Asteraceae family but is much smaller and very sticky. Below a photo shows
a little of the bees's yellow face.  © Carol Davis 8-27-2015

Curlycup Gumweed is a favorite of small bees and flies. Here is a link to another mining bee of the same
 species I found hanging out on some wild grass on the island a few weeks later. © Carol Davis 8-27-2015
