During the coming summer, you may find that too many Elephant Hawk Moth caterpillers are destroying a much-loved and valued Fuschia. It is possible to relocate all or some of these amazing but very hungry caterpillers. Obviously, Fuschias (from south America) are not the natural food of the caterpillers. They may be gently picked off the Fuschias at night, which is when they climb to feed, and transferred to plants in the willowherb family. If you can locate patches of the very common Rosebay Willowherb (Chamerion angustifolium) often found along roadsides or on waste ground or (even better) Great Willowherb (Epilobium hirsutum) often found beside canals or in damp areas, The caterpillers can be tucked in amongst the bases of the plants and at night they will climb to feed on their natural food.
