Hermit beetle  (Osmoderma eremita)

Elytra: In beetles and earwigs, the hard fore wings. They are held aloft when the insect flies, and are often coloured or patterned.
Larva: Stage in an animal's lifecycle after it hatches from the egg. Larvae are typically very different in appearance to adults; they are able to feed and move around but usually are unable to reproduce.
Pheromone: A chemical produced by an animal, which stimulates a behavioural or physiological response by another member of the same species.
Pollarded: A pollard is a tree with branches which have been cut back to the trunk so that is may produce a dense growth of new shoots.
Pronotum: In insects, the hardened cuticle on the upper surface of the first thoracic segment (the part of the body nearest the head).
Pupates: The process of forming a pupa, the stage in an insect's development when huge changes occur that reorganise the larval form into the adult form.
Vertebrates: Animals with a backbone.
