Synonyms and other taxonomic changes
A generic revision of Nearctic Scythrididae was published by Landry (1991). - Microleps.org
Sometimes listed as a subfamily of Oecophoridae
Scythrididae was designated as a subfamily, Scythridinae, of Xyloryctidae Meyrick
, 1890 (1)
by Hodges (1999).
Restored to family status by Heikkilä et al. (2013).
Explanation of Names
Author: Rebel, 1901
Xyloryctidae appears to be from Greek, xylon
, wood, plus Greek oriktes
, a digger (2)
. Some caterpillars of this family (apparently subfamily Xyloryctinae, not found in North America) are wood borers (Australian Xyloryctidae
). This is the same derivation as that of a scarab beetle, Xyloryctes
43 species in 6 genera in North America listed at All-Leps
About 650 species worldwide (Heikkilä et al. 2013)
Adult scythridids are small brown moths; some species are so dark as to appear black or blackish to the unaided eye, and some species have one or more whitish patches on the forewing. - Microleps.org
Some scythridids appear to be associated with sandy areas. - Microleps.org
most records: May-Sept, yr round in CA, AZ, TX (BG data)
In Illinois, scythridids show an affinity for nectaring during the day on flowers of yarrow, Achillea millefolium (Asteraceae) when it is in bloom. - Microleps.org
Larvae of the relatively few scythridid species for which life histories are known show a preference for feeding (usually internally, e.g., as leaf miners) on composites (Asteraceae). - Microleps.org
Adult scythridids are diurnal and seldom are attracted to light. - Microleps.org
