  Vancouver Looper

  Erannis vancouverensis is a geometrid moth occurring from northern British Columbia to central California. Larvae feed on young leaves of deciduous trees. Adults emerge during late autumn, with females being wingless. The species occasionally reaches infestation levels and is subject to natural population control through virus disease and tachinid fly parasitism.
