Triepeolus concavus, f, side, Pennington Co, South Dakota
Triepeolus concavus. Most Triepeolus bees are nest parasites of Melissodes, but a few interestingly have taken up with other groups of bees. This big one invades the nests of Svastra species...a group allied with Melissodes but a bit more robust and buff in their body.
This one collected in Badlands National Park. One of many places on the Earth I consider as a favorite.
