Pyroderces caesaris is a butterfly ( moth ) fromthe magnificent butterfly family (Cosmopterigidae).
features
The moths reach a wingspan of 13 to 15 millimeters. The front wings are ocher brown and have a silky white markings. Two narrow, elongated lines run in the anal fold and on the inner wing of the wing. A slanting inward band is 1/3 of the fore wing length. A similar, less sloping band is in the middle of the wing and does not reach the Costa loader . A very oblique outward line begins on the outer edge of the middle band. On the Costa loader there are some elongated lines that point towards the apex . A line runs from the interior angle to the wing tip. It is branched in the middle and points in the direction of the fringed scales on the inner edge of the wing. Most of the lines and spots have an irregular dark brown border. The fringed scales are ocher yellow at the apex and ocher gray to gray towards the inner wing edge.
In the male, the tegumen is trapezoidal. The right brachium is curved downward, the left brachium is curved inward. The blades are elongated. The upper edge is slightly concave and has a flat hump in the middle. The lower edge is almost straight. The aedeagus is trimmed and has a sclerotized basal ring. The anellar tube (manica) is straight and tapers slightly distally . The left valvella is long and slender and curved slightly inward. The right valvella is very short. The genital armature of the males is similar to that of Pyroderces argyrogrammos , but differs in the shape of the tegumen, the valve and the anellar tube.
In females, the sterigma is almost circular. The ostium is located in the upper left side of the sterigma and has a sclerotized, lobe-like process. The ductus bursae is slightly longer than the oval corpus bursae . The signa consist of two rounded, slightly sclerotized plates, which are provided with teeth made of tongue-shaped appendages of different sizes.
Similar species
In contrast to Pyroderces argyrogrammos , in Pyroderces caesaris the bandages on the forewings are more distinct and drawn through. The fringed scales are yellow ocher at the apex. The apical white ring of the tibiae of the hind legs is lined with brown on the inside.
distribution
Pyroderces caesaris is distributed from Spain across the Mediterranean to Turkey and the Ukraine ( Crimea ).
biology
The caterpillars develop on Echinops ruthenicus , Centaurea orientalis , split knapweed ( Centaurea salonitana ) and Cirsium sublaniflorum . They bore into the tubular flowers and mainly eat the young fruits. After overwintering, they eat the fruits of the previous year, but also quite often the pupae of other herbivorous insects. These include weevils (Curculionidae) and bored fly species (Tephritidae). The caterpillars pupate between the pappus of the fruit. The species forms one generation per year, the moths fly from the end of May to the beginning of autumn. The long flight time is due to the long and asynchronous development of the caterpillars.
