very big bees
The past couple of weeks I've been noticing some extremely large bees around my gardens, not visiting flowers, just flying around bumping into things.
Today I looked out and there were dozens of them, mostly around a large TX sage that's in bloom. I only saw one of them light on a flower, though. The rest acted like they were drunk, or maybe blind. I could hear them crashing into the siding from inside my house. These guys were big. And they were making a buzzy noise. None of them stayed put long enough for me to see any detail, but I didn't notice any yellow on them.
Can anyone figure out from this what type of bee they might have been, and tell me if they're likely to be at all aggressive. One of these days I'm going to have to mow out there. Tia -- Carol
