Look at what the office staff found crawling around Wilton Place today!
Apparently, about 20 of these little guys were crawling around by the office and library. After consulting the internet experts, I think they could be Mourning Cloak Butterfly larvae, Nimphalis antiopa. They like to eat elm, willow, wild rose, and poplar leaves. They can be pests in the garden, since the caterpillars eat a lot!
Have you seen any other caterpillars lately?
