Sign in to savethumb|A. radcliffei caterpillar thumb|A. radcliffei pupa Acronicta is a genus of noctuid moths containing about 150 species distributed mainly in the temperate Holarctic, with some in adjacent subtropical regions. The genus was erected by Carl Linnaeus in his 1758 10th edition of Systema Naturae. Caterpillars of most Acronicta species are unmistakable, with brightly colored hairy spikes, and often feed quite visibly on common foliate trees. The hairy spikes may contain poison, which cause itchy, painful, swollen rash in humans on contact. The larva of the smeared dagger moth (A. oblinita) is u

A. radcliffei oruga A. radcliffei pupa Acronicta es un género de lepidópteros que contiene unas 150 especies distribuidas principalmente en las regiones templadas del Holártico, con algunas en las regiones subtropicales adyacentes. Las orugas de la mayoría de las especies de Acronicta son inconfundibles, con matas de pelos de colores brillantes; se alimentan muy visiblemente en las hojas de muchos árboles comunes. La larva de la polilla Acronicta oblinita es inusualmente peluda, incluso para este género.[2] Las especies de Acronicta se conocen generalmente como polillas daga, ya que la mayoría tienen una o más marcas de puñales negro en la parte superior de sus alas anteriores. Sin embargo, algunas especies tienen una marca oscura en forma de anillo en su lugar.

thumb|A. radcliffei caterpillar thumb|A. radcliffei pupa Acronicta is a genus of noctuid moths containing about 150 species distributed mainly in the temperate Holarctic, with some in adjacent subtropical regions. The genus was erected by Carl Linnaeus in his 1758 10th edition of Systema Naturae. Caterpillars of most Acronicta species are unmistakable, with brightly colored hairy spikes, and often feed quite visibly on common foliate trees. The hairy spikes may contain poison, which cause itchy, painful, swollen rash in humans on contact. The larva of the smeared dagger moth (A. oblinita) is unusually hairy even for this genus. Acronicta species are generally known as dagger moths, as most have one or more black dagger-shaped markings on their forewing uppersides. But some species have a conspicuous dark ring marking instead.
==Description== Its eyes are naked and without eyelashes. The proboscis is fully developed. Antennae are simple in both sexes. Thorax and abdomen tuftless. Abdomen with long coarse hair on the dorsal part of proximal segments. Legs spineless. Forewings with non-crenulate cilia. Inner margin slightly lobed towards base.
