Identification and Appearance

Alfalfa Looper - Hodges#8466 - Tathorhynchus exsiccata
Contributed by Robin McLeod; Additional contributions by Maury Heiman , ceiseman

Adult: forewing light brownish-gray with diffuse dark shading beyond subterminal line; dark basal dash and dark strip between pale reniform and orbicular spots; reniform spot contains two dark dots; pale streaking along veins, and some dark speckling along costa; PM line faint or absent; fringe dark; hindwing pale gray or tan with large dark gray patch along upper two-thirds of outer margin; fringe pale except for some dark scales bordering the dark patch Apparently a taxonomically in-between species (and genus) whose classification has been difficult for taxonomists. In addition to the characteristics it shares with members of Catocalinae and Hypeninae, the adult's appearance also resembles some dart moths (Noctuinae) and some wainscots (Hadeninae).

About Butterflies and Moths: the wider group

Order-level background for Lepidoptera, the group containing Tathorhynchus exsiccata. Species-specific details appear above.

Group overview

Lepidoptera includes approximately 180,000 described species of butterflies and moths. Moths outnumber butterflies roughly 10:1. The monarch butterfly's eastern population has declined by more than 80% since the mid-1990s, and the western population by over 95% since the 1980s. The IUCN lists the migratory monarch as Vulnerable.

Ecological role of the group

Butterflies and moths are essential indicators of ecosystem health. As caterpillars, they are a primary food source for birds - a single nest of blue tit chicks requires ~10,000 caterpillars. Adult moths pollinate many night-blooming plants.

Economic and practical significance of the group

Lepidoptera are critical pollinators. In Europe, grassland butterfly species have declined by almost 50% since the early 1990s. In the UK, three-quarters of butterflies are in decline. In the U.S., five butterfly species have gone extinct since 1950, with 29 listed as endangered.
