Glossary

  • Crepuscular: active at twilight and/or just before sunrise.
  • Hibernation: a winter survival strategy characteristic of some mammals in which an animal’s metabolic rate slows down and a state of deep sleep is attained. Whilst hibernating, animals survive on stored reserves of fat that they have accumulated in summer. In insects, the correct term for hibernation is ‘diapause’, a temporary pause in development and growth. Any stage of the lifecycle (eggs, larvae, pupae or adults) may enter diapause, which is typically associated with winter.
  • 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.
  • Pheromone: a chemical produced by an animal, which stimulates a behavioural or physiological response by another member of the same species.
