I find Pine Hawk moths in my moth trap, unfortunately they are usually too tatty to photograph so I bought some Pine Hawks pupae from Worldwide Butterflies. I am patiently waiting to emerge for 2014 for some better pictures. I am growing Scots pine trees in pots to rear any caterpillars if I am successful in breeding Pine Hawk moths.
Pine Hawk-moth eggs start pale green changing yellow then to a reddish-brown and the caterpillars are green with white stripes along their body from head to tail and a brown dorsal stripe down its back which is more noticeable as it matures. It also has the characteristic hawk-moth 'horn' on its tail, which is red with a black tip. The stripes on the caterpillars make it well camouflaged on pine needles from which they feed.
The moths are greyish brown with dark streaks running down the centre of their wings maybe not so attractive as the caterpillars but brilliantly camouflaged resting on a tree bark like a Pine tree. The Pine Hawk-moth usually has one generation a year in the UK and can be seen flying from May to early August. Wings span is from 65mm to 80mm females. Food-plant Mainly Scots Pine.
