This is bumblebee. Like wild bees, only shaggy and not at all aggressive. Somehow they enter into my house in the autumn, and wake up in the spring and I have to let them out through the windows. And they make nests in the ground, somehow digging them. They produce honey, but they are wild, not used in apiaries. One of the best insect pollinators here.Pasha, what is the little brown thing looking out your window
Specifically, this bumblebee is the third one that I let out the window in that day.
