Juniper Seed Caterpillar (Marcovitch)
Synonyms and other taxonomic changes
Argyresthia alternatella Kearfott, 1908
(1)
Gelechia alternatella
Phylogenetic sequence #360141
Explanation of Names
Specific epithet is meant as an alternative to "
A. cupressella Wlsm. (described from California) which they superficially resemble."
(1)Numbers
52 spp in genus north of Mexico per Arnett (1985)
(2)Size
Wingspan 10-12 mm (Kearfott, 1908; Marcovitch, 1915).
Larva to 7 mm (Marcovitch, 1915).
Pupa about 4 mm (Marcovitch, 1915).
Identification
Larva - see Marcovitch description available through Print References below.
Adult - see both Kearfott and Marcovitch descriptions below.
(1)Range
MPG records as of May, 2013 indicate a range from western Texas north to Minnesota, east to southern Quebec and Massachusetts, southwest through New Jersey, Kentucky and on to Alabama. However, Braun collected them at 5175' in Glacier National Park, Montana so the range is presumably much wider.

Type Location: Essex County, New Jersey.
(1)Food
Larvae feed on the berries of
eastern redcedar (
Juniperus virginiana, Cupressaceae) (Marcovitch, 1915). Note: Braun collected the adults in Montana, well outside the USDA range data of this host.
Life Cycle
Eggs laid on stems just below below juniper berries. Full-grown larvae leave the seed and build white silken cocoons, presumably on the plant, in which they pupate (Marcovitch, 1915).
