Cocoon: a sheath of silk, which is spun around the pupae of some insects (a pupa is a stage in an insect’s development, when huge changes occur that reorganise the larval form into the adult form. In butterflies the pupa is also called a chrysalis).
Fennoscandia: a geographic term used to describe the Scandinavian Peninsula, the Kola Peninsula, Karelia and Finland.
Larvae: 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.
Metamorphosis: an abrupt physical change from the larval to the adult form.
Pupate: 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. In butterflies the pupa is also called a chrysalis.
Subspecies: a different race of a species, which is geographically separated from other populations of that species.
