The privet hawk-moth is a very large hawk-moth that is on the wing for a short period in June and July. It is commonly found in parks and gardens, as well as woodland. The adults are attractive, but it is the large caterpillars that really catch the eye: lime-green with a purple blush, purple-and-white streaks on the side, a pale yellow spot on each segment, and a big, blackish hook at the tail end. The caterpillars feed mainly on privet, but also on ash and lilac leaves. As they mature, they turn pinkish and burrow deep into soil in order to pupate, hatching out the following summer.
