Hibernation is a exiting topic. And I can see that there are a lot of diffrent approaches to it.
I´ve been keeping european insects for some years now. And some of them really need hibernation, because of their life cycle. Some water bugs for an example only needs hibernation during their larvea periode, and while they are in the pupae. But as adults they can live well for years without it. Other insects has seasonal lifecycles that requires a lowering of temperature. But all of these insects are limited, because they NEED the hibernation factor to start or relay certain factors in their life cycle. There are numerous amount of insects that only do hibernate to avoid diffrent unsuitable conditions, not because they need the hibernation as a factor. Just think of the common housefly, it does not need hibernation. But it can hibernate if conditions get too extreme.
My point is that there MUST be ants that don´t need hibernation as an factor, but still is able to hibernate. I write MUST, because ants have been such a succesfull group of insects so somewhere it has too. So many other groups of insects, also long living ones, are able to hibernate when they live in cold climate. And when they live in warmer regions of the world, they don´t hibernate.
I must try it out with Myrmica rubra, when spring comes.
the only european species that doesn't need hibernation is Aphaenogaster senilis
Then I must search for information about A. senilis.
What is Your knowledge about A. senilis hibernation based on, is it litterature, the internet or experience?
Do You know any scientific research about ants and hibernation?
Hi Scáth-Siorrai!
Where do You have Your information about A. senilis from. Please I would like to know!

I keept Myrmica rubra for many years without Hibernation. So it doesn´t need it to survive. But its right, that the live of the Queen could shortend and that the colony is growthing slower. But you can keep it without hibernation.
And for example look at Formica fusca. If you have a sunny day in January (and more than 10°C) you can see them active!
So, for some species, the hibernation is more an adaptation to the bad conditions outside. I am sure, that you can keep F. fusca with a very short hibernation time or even without hibernation. But may be, the life time will be shorter.
It is not right to say, that the fact, that a ant does hibernation that it also need hibernation.
they can probably survive without it but that doesn't mean they don't need it either.the ants are less healthy/active without it and the queens lay a tiny amount of eggs...
Hi
I believe that a coloni that live in temperated climate, which does not hibernate probaly will have a shorter lifespan. And maybe it will also be a stronger, and more fastgrowing coloni.
I think that the way I used the word ´need´in this contects, was like Jogi does. My concern was if any european ant specie need hibernation to survive. But that does not mean that Scáth-Siorrai are wrong. I´ve made my decision, I´ll try with a Myrmica rubra when spring comes.
