Ynghylch

The lime hawk-moth is a large hawk-moth, on the wing from May to July. It is commonly found in parks and gardens, as well as woodland, but flies only on warm nights. The caterpillars are quite distinctive: large and green, with pale streaks on each segment and a bluish 'horn' at the tail end. They feed at night on the leaves of lime, silver birch and elm, but the adults don't feed at all. During the day, the adults rest to avoid catching the attention of predators. This species hibernates as a chrysalis.

Sut i'w hadnabod

The lime hawk-moth is a pinky-buff colour, with greyish-green at the tip and base of the wings, and two large, dark green patches half way along the forewings. It holds its wings to form the shape of a right-angled triangle. The back edge of the wing is scalloped to aid camouflage.

Dosbarthiad

Found in England and Wales.

Hawk-moth caterpillars can be easily recognised as a group because they are hairless and have a noticeable curved 'horn' at the tail end.
