Deilephila Elpenor Caterpillar Looks Like A Snake

The preferred food plants of the caterpillar are willowherb (Epilobium) and bedstraw (Galium), though it will also take fuchsias.
• Adult
The imago (adult) feeds at night, and often takes nectar from garden plants like Honeysuckles (Lonicera) and petunias, so it is quite often seen in urban settings in the evening. The moth typically has a wing span of 50–70 mm (2.0–2.8 in). It is spectacularly coloured, seeming to shimmer with green and red when in motion. The adult moths are eaten by some species of bats.
