features

butterfly

The wingspan of the moth is 17 to 24 millimeters. The basic color of the forewings varies from gray-brown to red-brown. Some dark spots can be seen on the front edge. The light wavy line near the hem is broken up into white spots, of which the spot at the inner corner is particularly prominent and is sometimes created twice. The clear black central point is elongated. The hind wings are slightly lighter than the fore wings. There is often a small white spot at the anal corner.

Egg, caterpillar, pupa

The egg is glossy white in color and has a smooth surface.

The caterpillars are greenish in spring, reddish or brownish in color in late summer and show very clear red-brown angular spots on the back. The color corresponds to the leaf or fruit status of the forage plant.

The yellow-brown doll has green wing sheaths and is equipped with two strong and six thin hook bristles on the cremaster .

Similar species

The ragwort moth ( Eupithecia absinthiata ) has very similar drawing elements. In this type, however, the white point at the interior angle is weaker or absent. A genital morphological examination can be helpful in determining.

Geographical distribution and occurrence

The hop pussycat is widespread in Europe. Its occurrence extends east to the Urals , the Ussuri region and further to the Sakhalin Island . In the Pyrenees and the Alps , it rises to heights of 1500 and 1800 meters respectively. Another distribution area is in North America. The species prefers moist forest edges, shady hedges and riparian regions.

Way of life

The moths are crepuscular and nocturnal and fly in two generations from late April to late June and from July to September. Sometimes they suckle on the blossoms of elder ( Sambucus ) or ash species ( Fraxinus ). They also appear in artificial light sources . The caterpillars initially feed on the leaves of the real hops ( Humulus lupulus ), later also on the flowers and fruits. In North America they live on currant species ( Ribes ). The second generation pupae overwinter.

Danger

In Germany, the hop bloom moth occurs in all federal states and is listed on the red list of endangered species as "not endangered". Only in Saarland is it considered "critically endangered".
