Pear tree attack

One of the pear trees has been colonised by these tiny tent caterpillars. Well, they're tiny now, but if they keep going like this I imagine they'll soon be enormous.

And in other insect news, it has finally got warm enough for the annual cicadas (Tibicen linnei) to emerge. I've never seen one, but you can't mistake the song the males sing:

Egads, those pictures of the caterpillars are disturbing. Good luck!
