Walked into my barn today and there were bees all over a pile of oak firewood that I had thrown in there to stay dry and season. At first I thought my bees were attracted to the wood for some weird reason until I got closer and seen that they were actually going in and out of small holes and crevices in the wood. Then it dawned on me that they were a native bee of some kind. They are very close to looking like a honey bee except they are more of earthy brown fuzz with darker to black abdomens. I tried for a pic but they are very active. I haven't found a good internet pic to compare them to but I'd like to know what I got and how I can help them. Some articles I found mentioned homemade nest cavities by drilling holes in oak logs for them to use. I'm trying to find out about their life cycle and stuff. Like will they occupy the wood from here on out or are they just a seasonal thing and then I can have my wood pile back, it's my backyard fire wood pile but I'll sacrifice it for them. I actually feel kind of blessed in a sense that I've got them so I want to do right by them. So looking for any kind of guidance here. Thanks.
