Anthophora bomboides is highly colour-variable, but recognition of most subspecies is not warranted. Here are two of the “subspecies” nesting together in the same bank - its nest parasites, Triepeolus dacotensis was also present. #beesofcanada #cuckoobees #diggerbees #macrophotography #beenests

A #nesting aggregation of Diadasia australis we found in 2023. This #bee is a specialist on #cactus flowers, and females returning to the nesting site were covered with the pale yellow Opuntia #pollen #BeesOfCanada #BeeNests #bees #badlands #Saskatchewan

Anthophora peritomae is the only Micranthophora known from 🇨🇦. It regularly visits #gumweed, but likely requires hard vertical banks for #nesting; it is < 10 bee species that excavates its nest into #sandstone. It is rather uncommon in 🇨🇦 #beesofcanada #bees #beenests #nesting #prairiebees #sandstone

A resin bee carrying resin - Megachile campanulae (Robertson), a species that we found in SK only a few years ago. The opened nest shows the single brood cell containing a larva, busy eating the pollen & nectar mixture! #beesofcanada #resinbees #beecondo #beenests #macrophotography
