The Eustrotiinae are a subfamily of butterflies from the family of the owl butterflies (Noctuidae). The subfamily includes around 200 species.

features

The moths are relatively small to medium-sized and have a wingspan of about 15 to 40 millimeters, most species are only 15 to 25 millimeters in size. The wings are relatively wide with a rounded apex . The forewings are usually brightly colored and clearly drawn. Usually all cross lines and blemishes are developed. The wing veins R3 and R4 are approximately the same length. The hind wings, however, are uniformly colored and often gray. The M2 wire is often present, but slightly shortened compared to M3. It hits the cell about 3/4 the length of the cell.

The antennae are ciliate in the males, tufted with few bristles in the females. The forehead is smooth and rounded, the labial palps short and more or less curved upwards. The second segment is two to three times longer than the third, cylindrical segment. The tibia has no spurs. The abdomen usually has one to four ridges on the back that sit on segments one to five.

The caterpillars have three SV setae on the first abdominal segment.

Geographical occurrence and habitat

The types of the subfamily occur worldwide; however, most genera are native to the tropics . The species live in very different habitats, but more in open areas where the caterpillars' food plants grow.

Way of life

The moths usually fly in the sunshine during the day, but also at night. They are attracted to artificial light sources . The caterpillars of many species are oligophagous and prefer to feed on herbaceous plants , especially on sweet grasses (Poaceae) and sour grass plants (Cyperaceae).

Systematics

The Eustrotiinae were often included in the Acontiinae , but interpreted by Fibiger & Lafontaine (2005) as an independent subfamily. The systematic scope is very uncertain. In the database "Butterflies and Moths of the World - Generic Names and their Type-species" of the Natural History Museum London, the genus group around Eublemma is included. This group is described by Kravchenko et al. (2007) regarded as a separate subfamily Eublemminae. The Eustrotiinae are probably paraphyletic . Only European species are listed (according to Fibiger et al. (2009)).
