Glanville Larvae wake up

Our colony of Glanvilles is still on the go. Overwintering larvae have now woken up, due to the warm weather, and have been eating for about two weeks, they have just gone into the 6th instar, as seen below the ones with the bigger heads. Hopefully the Glanville will be seen flying on its Croydon site in May and June, as it has for the last 3 Years.
