Elephant Hawk-moth (Deilephila elpenor)
This moth loves Honeysuckle and feeds on it at night although the larvae prefers members of the Willowherb or Bedstraw families of flowers. The larvae over winters as a pupa.
This is widespread species and quite common during May to July. In Dorset we sometimes see a second brood later in the year with these insects turning up in September and even October..
