Satyrodes eurydice ( Syn. Lethe eurydice ) is a butterfly (day butterfly ) from the family of the noble butterfly (Nymphalidae).

features

butterfly

The wingspan of the moth is 38 to 62 millimeters. Fore and hind wings are brown in color on top. The post-fiscal region is slightly brighter. There are four black eye spots on the upper fore wing. The upper side of the hind wings is provided with five to six black eye-spots, which are strung together like a chain. The undersides of the wings are lighter brown. The eye spots on the upper side shine through, but are usually white or light blue with a core. Thin, dark transverse lines run on the underside of the hind wings, the outermost of which is strongly jagged.

egg

The eggs are green-white and are laid individually, but rather randomly, on different food plants.

Caterpillar

Adult caterpillars are green in color, with a dark green topline and yellowish side stripes. The body ends in two points. There are two reddish horns on the head.

Doll

The falling doll has a green base color and is provided with yellow side stripes. There is a hump behind the head.

Similar species

Satyrodes appalachia differs slightly in the less jagged outer transverse line on the underside of the hind wing. This species is mainly found in forests.

Subspecies

In addition to the nominated form Satyrodes eurydice eurydice , another subspecies is distinguished:

  • Satyrodes eurydice fumosa (Leussler, 1916)

Distribution and occurrence

The range of the species extends from the south of the central and eastern Canadian provinces and further south through the central and the northeast of the USA . Satyrodes eurydice prefers to colonize open grasslands.

Way of life

The moths usually fly in one generation in June and July. A second generation sometimes appears very locally in August. They rarely visit flowers to take in nectar. They also only occasionally suckle on injured trees. Various sourgrass plants (Cyperaceae) are named as food plants for the caterpillars , for example beak sedge ( Carex rostrata ), Carex lacustris , Carex bromoides , Carex trichocarpa , Carex lupulina , and Carex stricta . The caterpillar overwinters in the third or fourth instar.
