FYI if you don’t know them: do not touch , kill with fire or something. Don’t let your dog near them
Yeah, that looks like oak processionaries. They can cause skin irritation and apparently asthma, too..
Noctuoneida (or something like that), Owlet Moths.
No, we do not kill anything unless they are definitely invasive, which these guys aren’t. They are only a problem if you happen to sit on one, (and you happen to be naked, I suppose) generally they are not a nuisance at all. They stay in their tree, dispersing to eat during the day, and getting back together in clumps like this at night.
These processionary caterpillar are invasive. They kill pine and alike. https://www.standard.co.uk/news/uk/defra-england-france-europe-north-africa-b995054.html
there's no such thing as an animal or plant that is invasive in the general sense
when you say something is invasive, you need to specify where
As per the linked article.
I’m all good with comments about protecting these caterpillars, I just hope we are not neighbors 😉
Again, they are not invasive here.
Where are you located?
Southern Africa.
No, don't kill them OP. They didn't ask to be born a venomous critter. They're just trying to live their best life. Please don't kill them :(
Do as you please. But you may want to check for local regulations and pest control advices about these caterpillars.
I never kill anything unless absolutely sure. Even then I hesitate.
They're blue tit food! The reason they're out of control is that there aren't enough birds to eat them.
