features

bile

The spherical bile , up to 15 mm in size, with long hair on the outside , is initially white, later mostly green or bright red. Several of the single-chambered and thin-walled galls can grow together into irregular structures. It usually sits on the underside of the leaf, but can also appear on the upper side, the petiole or the stem. The galls have a central larval chamber with a star-shaped, spongy tissue.

Gall wasp

The whole compact body of the Gundermann gall wasp is less shiny black than that of the blackberry gall wasp ( Diastrophus rubi ). It is only finely wrinkled on the middle chest ring and longitudinally wrinkled on the almost hemispherical, two-pod at the root, label. The front chest ring is hairy. The legs are reddish brown or lighter. The yellow-red, thread-like antennae consist of thirteen to fourteen segments, in the male also of fifteen. The females become 2.6-3 mm long.

Occurrence

The bile is found on Gundermann ( Glechoma hederacea ) and Longhair Gundelrebe ( Glechoma hirsuta ) from June to September . In some years it is common to very common and in others it rarely occurs.

The species is widespread in the western Palearctic , evidence is also available from Kazakhstan in Central Asia. Together with its host species, it was imported to North America, where it is naturalized and not uncommon.

Parasites

The wasp Torymus glechomae Mayr, parasitizes the larvae of the Gundermann gall wasp. With a long ovipositor she lays her egg in the chamber on top of the larva in the gall.
