Andrena gardineriObserver
joegiulianDescription
This female keys to Andrena gardineri in Mitchell (1960) and LaBerge (1967); also, to Callandrena in LaBerge (1985)’s subgeneric key. A tad early for this bee, but iNaturalist observations at this site show Packera is well into bloom by now.
Selection of initial characters in Discoverlife also leads to A. gardineri, A. hirticincta, A. rubi, and A. rudbeckiae; it cannot be the latter 3 for numerous reasons, especially the flight season and facial characters.
I attempted to photograph the bidentate labral process, hyaline tergal rims, among other key cool features of this bee.

Keys to Andrena erythronii. Pictures show a distinct but weak pronotal angle, flat clypeus with median impunctate line, wide but slightly emarginate labral process, impunctate abdomen without strong fasciae, linear malar space. Foveae are ~2/3 space, propodeum is not rugose or striate as in Trach/Scrapt. Pale vestiture, nothing fuscous or black.
