Well, this doesn't really all have to do with beekeeping involving honeybees, but anyway. Today I went out on our balcony in the early evening to look at the moon with my telescope. It was below freezing by at least a few degrees, maybe even five. Then I noticed a paper wasp lying on it's back on the deck, quite dead looking. I decided I'll take it inside, I'm not sure why though. I was pretty sure it was dead, but I just felt I'd take it in anyway. So I brought it in and placed it on a plastic container lid. I thought I'd try to revive it by letting it warm up and see what happened. I grabbed a container too to make sure it wouldn't escape if it did wake up. So I blew on it a little and poked it with a piece of paper. Then it's leg twitched. I poked it a bit more (again it twitched in response) and suddenly it came completely to life, waving it's legs (it was still on it's back). Well, now I have it safely in a glass bowl with a screen lid and some sticks (I made it to keep jumping spiders in). I fed it honey and sugar water too. But now this incident made me wonder. I found this wasp on a below freezing January day out in the open, yet now it's very much alive in the house. I've always heard that most worker wasps die in the fall, while few are able to hibernate. I know honey bees don't hibernate, they stay safe in the hive all winter. But how much cold can a bee/wasp stand before it dies? It was cold all day today, so the wasp would have had to have been out there for a while. It seems to be fine now though. Would it be possible to bring back a hive that's been pronounced dead from the cold? If your bees were alive yesterday but are dead today, grab a sack of them and bring them inside. Maybe they'll come back to life.
