Lesser Yellow Underwing

Noctua comes – This moth caterpillar almost turned a darker shade of  oak on Saturday when I was staining my back fence. Thankfully I spotted it in time and relocated it near a similar foodplant opposite, stopping to take a few snaps of it. The image below shows it rolled up in defensive mode, making it look less like a caterpillar to a prying bird. The head is in the centre with its suckered, almost toothed feet (prolegs) and front legs (true legs) like fingernails wrapped around it. Double click for a better look.

Lesser Yellow Underwing Noctua comes

It may have just come out of winter hibernation (or I inadvertently woke it up). It is not a fussy eater and will feed on a range of bushes, trees and herbaceous plants. It tends to feed at night, then hides from predation during the day. It will eventually pupate underground before becoming the adult.
