Congrats @ph1102!!
"This hard work appears to pay off, however, by providing the bees greater protection from the vagaries of life in the desert Southwest. The species, dubbed Anthophora pueblo, has been found in Utah, in southwest Colorado and in Death Valley in California, where it pocks vertical sandstone rock faces with tiny holes. Though the bees seem to be solitary nesters, they build these rocky alcoves next to one another, like insect apartment-dwellers."
