Udea abstrusa - Hodges#5100
Udea abstrusa
This record describes Udea abstrusa (species). Recorded family: Crambidae. Recorded order: Lepidoptera.
Identification and Appearance
Similar in size and appearance to itysalis and radiosalis . Labial palpus 3.5 to 4 times as long as diameter of eye, exceeding head by 1.25 to 1.5 times length of latter. Antenna of male compressed, of female filiform, pubescent in both sexes, but with longer pubescence in male than in female. From itysalis this species differs most regularly in lacking the subapical interruption of the subterminal dark shade. From radiosalis the male can be distinguished in that it has the outer preapical spur of the hind tibia well developed as in itysalis , not rudimentary, as in radiosalis . Females tend to be browner than those of radiosalis , but they cannot always be distinguished with certainty.

About Butterflies and Moths: the wider group
Order-level background for Lepidoptera, the group containing Udea abstrusa. 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.
