Synonyms and other taxonomic changes
Siederia walshella is a new combination proposed by Peter Hättenschwiler (see notes on this page by Jean-François Landry). Landry places Dahlica and Siederia in subfamily Naryciinae.
Numbers
26 species in 13 genera in North America listed at All-Leps
Size
Male wingspan 12 - 36 mm
Identification
Adult females are either wingless or have only little vestigial stubs where wings should be. Males are usually black and unmarked.(1)

Larvae (bagworms) construct elaborate little cases around themselves of plant debris and other organic matter.

Range
cosmopolitan
Food
Larvae of some species eat lichen, whereas others prefer green leaves of a hostplant (usually a deciduous or coniferous tree).
Adults do not feed.
Life Cycle
Larvae (bagworms) construct spindle-shaped bags covered with pieces of twigs, leaves, etc., and remain in them -- enlarging the bags as they grow -- until they pupate (also in the bag). Adult females remain in the bag, emitting pheromones which attract adult males to mate with them.

See

Eggs are laid inside the bag, and when they hatch the larvae crawl away to begin construction of their own individual cases.

Some bagworm species are parthenogenetic; their eggs hatch without being fertilized.
