Question about diapause

Megahile li lied, but about anlren H. Z. There are many of them and not all biology is well studied. The micrandren that I see in late autumn are very similar to those that I see in early spring.

The process of entering diapause is complex biochemically and physiologically. In the body, all physiological processes slow down and "antifreeze" should begin to be produced, which allows you not to freeze through - in insects, these are usually glycerol derivatives. To do this, eat high-calorie food. An insect brought out of diapause by unexpected heat for the second time does not have enough food (if there is any at all), nor time to prepare. So...sleep better byloa

You write about something that you have very little idea about. First, there are two alternative mechanisms of insect hibernation: either due to the difficulty of freezing (typical, in particular, for hymenoptera), or vice versa, due to its facilitation, but without the formation of pointed crystals (for example, some beetles). But in both cases, a strict one-time process is completely optional. Many insects repeatedly wake up during the winter and crawl over, or even fly to other shelters, as the original ones are flooded. And at some soldier bug on the wall with a southern exposure in sunny weather, grbernation begins every evening and ends every morning, and so 3-4 months in a row. And all this time they practically do not eat, because it is too cold for digestion. And nothing survives somehow, although not everyone is lucky.
