Mompha ochraceella is a butterfly ( moth ) fromthe fringed moth family (Momphidae).
features
The moths reach a wingspan of 14 to 16 millimeters. The forewings are yellow ocher and have four clusters of protruding scales . Two are brown to dark brown and are located in the first fifth and in the middle of the inner wing edge. An ocher-colored tuft is located near the base of the forewing, a white tuft is in the costal fold between the two dark brown tufts. The hind wings shine yellowish white.
In the males the uncus is strong, the cucullus is more than eight times longer than it is wide. The saccule is wide and gradually tapers from the middle and then abruptly tapering to a blunt apex. He reaches the top of the Cucullus. The gnathos is large and apically rounded. The annellus lobes are 1/3 as long as the aedeagus and dilate distally . The aedeagus has a hook-shaped cornutus.
In the females, the eighth tergite is wide, the non- sclerotized part of the posterior margin is clearly pronounced and U-shaped. The sclerotization of the postvaginal lamella and the antevaginal lamella are partially fused. They are wide, have distally U-shaped dimples and a protruding side. The vaginal sinus is large and flat. The posterior part of the ductus bursae is funnel-shaped and has club-shaped sclerosis in the center, which are more than half as wide as the ductus. The anterior part is weakly sclerotized.
distribution
The species is native to the Western Palearctic . The distribution area extends in northern Europe to southern Sweden . In the south, the species occurs in Morocco and Asia Minor . In the east the distribution area extends to the Caucasus and Iran . In Central Europe , the species is widespread, it occurs in damp places along streams, rivers and lake shores.
biology
The caterpillars develop on the shaggy fireweed ( Epilobium hirsutum ). They live in the stems from summer to autumn, creating irregular feeding tunnels filled with brown caterpillar droppings. In autumn they change to the roots to overwinter. In the coming spring the caterpillars drill a feeding tunnel into the lower part of the stem and create vesicle-shaped mines on the underside of the lower leaves. The caterpillars change the mines partly via the feeding tunnel in the stem. They pupate in a mine in a whitish silky cocoon . The species forms one generation per year, the moths fly from late May to mid-August.
