Female :) with her four bands. Beautiful girl. New season bee.
They can sting as I found out when I saved one from inside the house with nothing but a tea towel between us. Unlike honey bees, stinging doesn’t kill them… apparently – I’ve never found any info stating this categorically but the one that stung me flew off to enjoy life to it’s full.
I believe it’s their ovipositor they use to sting with, so the males don’t. And it’s not a barbed stinger like the EU honey bee, so doesn’t get left behind and ruin the bee’s body. The logic is because they are solitary bees they are not expendable, don’t lose their stinger, like the hive honey bee that is expendable, to the hive.
