Lampyrrida e
FamiIyPHENGODIDAE glowworrns
J. McNq.mara
Only one species of Phengodidae occurs in
Canada. The larvae of most species are luminescent,
hertce the vernacular name glowworms. The
larvae fe,,ed on soft-bodied insects and other small
organisrls. The females are larviform but have
compound, instead of simple, eyes. Adults and larvae
occur in leaf litter and under logs, bark, and
debris on the ground. The males are al;tracted to
light
Ẇittmer .1975) revised the North American
species of the genus Phengodes, the only genus
occurring in Canada.

Familv LAMPYRIDAE fireflies
J. McNamara
Twenty-nine species of Lampyridae are
recorded in Canada. Members of this family are
fairly well known because of their ability to produce
flashing light. Species may be recognized in flight
by the color of the light as well as by the number
and the length of flashes. This flashing behavior
enables l;he sexes to frnd each other. All larvae and
most adults are luminescent. The larvae are predaceous
and feed on other insects, larvae. snails, and
slugs. The feeding habits of the adults are not well
known.
Many genera of lampyrids have been revised in
the past few decades, but a thorough revision ofthe
family would be very useful. Green (1948) published
a revision of the Nearctic genera.
