Since the old photo album has not been migrated from the old forum, I'm going back to the most interesting pictures.
Here are 2 from SixK on the larvae and ladybug eggs that eat the ugly aphids:

Re: Eggs and ladybug larvae: recognize them!
Seen in my shed at the bottom of the garden on a corner of the roof...a crowd of ladybugs...probably to spend the winter...
It resists frost at how many °C the ladybugs because the shed is far from being frost-free!

Re: Eggs and ladybug larvae: recognize them!
It's the Asian ladybugs that spend the winter like that. Not the natives. In our room (never heated), one year there were clusters of several hundred in the window corners..

The whole story of the invasion https://france3-regions.francetvinfo.fr ... 52776.html
Basically: a non-invasive hybrid was created by INRA in the 80s, then marketed by Biotop

It's not just Asians who can hibernate in a house.But the biological scenario goes wrong. In parallel with this marketing, other contingents of Harmonia Axyridis arrive in France clandestinely. "From 2003, the Asian ladybug entered French territory from Belgium, which it had colonized. It is now very present everywhere in the plains of the Grand Est, as in all regions of France", observes Raynald Moratin, scientific manager of Odonat, the naturalist data office of the Grand Est, a federation of naturalist associations in the region...
Also observed are ladybugs from the American continent, where they had also been introduced by man. “We analyzed the genome of invasive ladybugs in France, explains Arnaud Estoup. We find a fraction of genes from the Inra strain and a large proportion of genes from Asian ladybugs from North America. hybrid that has been spreading in the north-east of France, especially in Alsace, for ten years."
A hybrid that has raised many controversies, to the point that the company Biotop decided in 2011 to stop marketing this ladybug as a natural insecticide. "We decided to replace it with other species, such as 2-point and 11-point ladybugs," says Biotop's marketing manager.

It's rarer. They are solitary unlike the Asians who gather.
