features

The moths reach a wingspan of 8 to 11 millimeters. The head shines golden to golden ocher. On the sides there is a white line above the compound eyes . The antennae shine brown, the first two thirds are ringed white. The last third has five white sections, each separated by three dark brown segments. Thorax and tegulae shine gold. The tegulae are lined with silver at the back. The front wings shine golden, the Costa loader has a brownish edge. There is a pale gold line on the base of the wing. An outwardly directed white costal line begins at 1/6 of the forewing length. It is lined with pale gold and extends beyond the Costa loader. The wing markings include two white, more or less dark brown-edged costal spots. The first is in the middle of the Costa loader and is connected to an underlying pale gold spot. The second is 3/4 of the fore wing length and is lined with a few pale golden scales . On the inner edge of the wing there are three raised, pale gold, dark brown-edged spots. The first is on the anal fold between the costal line and the first costal spot. The second and largest spot is on the inner wing edge between the first and second costal spot. The third is on the interior corner . At the apex there are small raised pale golden spots and some golden and dark brown scales. The fringed scales are gray-brown. The hind wings shine gray-brown. The abdomen is gray, the segments are banded whitish behind.

In the males, the tegumen narrows distally and has a “U” -shaped bulge at the back. The right brachium is curved and tapers to the apex. It's not quite twice as long as the one on the left. The left brachium is only slightly curved and has a pointed apex. The blades are pear-shaped. The right valvella is very large, much longer than the tubular section of the aedeagus, and strongly curved downwards. The left valvella is reduced. The tubular part of the aedeagus is almost straight, the basal part is large and bulbous.

In females, the eighth segment tapers slightly distally. The ostium has a semicircular and heavily sclerotized anterior end. The seventh sternite has a distinct triangular sclerotization behind. The ductus bursae is narrow and as long as the corpus bursae . The corpus bursae is oval and has two cup-shaped signs.

distribution

Isidiella nickerlii is native to Central and Southern Europe . The distribution area extends from the Iberian Peninsula in the west to the Balkan Peninsula in the east.

biology

The caterpillars develop on common yarrow ( Achillea millefolium ) and straw flower ( Helichrysum arenarium ). They live on the young terminal leaves of the host plant in a web. The moths were collected from May to July.
