moth

Caddisflies, of which there are about 200 species in the UK, look similar to moths and have hairy wings.

Prof Russell Wynn, Director of Wild New Forest, said the Little Arboreal Ladybird's had been found in moth traps across the New Forest but "there were no confirmed British Records prior to this influx".

Harley is a rescue hound, of indeterminate but clearly mixed breed, who is given to leaping in the air to snap at moths and making vain but enthusiastic attempts to catch lizards.

While some gleefully joined in the mauling, others were attracted to the film like moths to a flame.

The researchers did a series of carefully controlled experiments to ensure that the moths were responding to the sound and not the appearance of the plants.
