Tetracis cachexiata Guenée, A., [1858] in Boisduval, J. B. A. de & Guenée, A., Histoire naturelle des insectes. Species général des lépidoptères, Paris, vol. 9:142. Holotype ♀, “ Nouvelle-Hollande ” [ Australia], incorrect locality, actually North America [MNHU].
T. lorata Grote, A. R., 1864 . Proceedings of the Entomological Society of Philadelphia, 3:91. Syntypes ♂, ♀, Eastern and Middle States [ USA]. Location of types unknown. Note: After his death, the specimens in Grote’s collection were scattered and many were damaged or destroyed.
Diagnosis: Recognized by white or creamy-white wings, DFW transverse pale brown PM line, absent AM line and discal spot.
Description: Adults ( Figs. 16–18 View FIGURES 12 – 26 ): FWL: 19–26 mm. Antenna (stated as prismatic by some authors) essentially filiform, ventrally minutely setose, thinner in females. Palpi, upcurved, short (about to horizontal midline of eye), tan scales on outer side, paler inward. Head, thorax, abdomen, legs, wings concolorous varying across individuals from white to creamy-white; tarsal spines brown. Wings: DFW with thin straight brown transverse PM line from apex to inner margin (sometimes indistinct) discal spot absent; DHW unmarked. Underside unmaculated. Male genitalia ( Figs. 88 View FIGURES 87 – 94 , 103 View FIGURES 102 – 117 ): Uncus decurved, slender, tapering to pointed apex. Gnathos with pair of robust upcuved spines projecting from dorso-caudal margin. Stubby furca from middle of anellus tapers to rounded apex. Valve broad, tapering slightly to rounded apex lacking an apical projection. Aedeagus with incomplete ring of widely-spaced spinules at posterior end at base of vesica; everted vesica elongate with expanded midsection on which is situated an oblong sclerotized plate containing short spinules. Female genitalia ( Fig. 119 View FIGURES 118 – 124 ): A/P = 0.55. Very short, linearly sclerotized ductus bursae expands to join unsclerotized sack-like corpus bursae. Signum oval and strongly dentate.
Material examined: Numerous specimens, number not recorded; two dissections in addition to examination of genitalic illustrations in the literature.
Biology: Life history by Forbes (1948) and McGuffin (1987:84). Many recorded larval hosts, some of which are Alnus , Betula , Prunus , Salix , Tilia , Ulmus , Viburnum , Abies , Larix , Pinus , Tsuga . See also Heppner, 2003, p. 348. Adults May—early July, depending upon locality. A montane and piedmont species.
