Tingis ampliata is a bug from the family of net bugs (Tingidae).

features

The bugs are 3.7 to 4.2 millimeters long. Species of the genus Tingis are gray-brown in color and coated with white, powdery wax excretions. The fourth part of the antennae is wider than the third and there are three small appendages on the head between the eyes. Tingis ampliata can be identified by the four rows of cells at the edge of the pronotum network . Two processes behind the eyes extend beyond the base of the three processes further forward.

distribution and habitat

The species is common in Europe, with the exception of the north and the Mediterranean countries. In the east the distribution extends to Siberia, China and Japan. It is widespread in Central Europe, but much more common in the north than in the south. In the north German lowlands it is sometimes more common than Tingis cardui and can occur together with this species. The species is widespread in Great Britain.

Way of life

The animals live mainly on field thistle ( Cirsium arvense ), less often on other seared thistle ( Cirsium ) such as swamp thistle ( Cirsium palustre ) and common seared thistle ( Cirsium vulgare ). The nymphs and adults sit on the leaves, in the leaf axils and less often between the spines on the outside of the flower heads. In spite of their fully developed wings, the adults are airborne and only fly short distances, if at all. Hibernation takes place as an imago in the litter under the thistles. They appear again from April, sometimes even on warm days in the middle of winter, and then sit on the basal leaves of the plants. Mating takes place in April, eggs are laid in May and June. The females pierce their eggs individually or in small groups along the nerves into the leaf tissue. The puncture site turns brown. The nymphs appear from May or June, the adults of the new generation from August. The young nymphs stay on the leaves where their eggs were laid. Only later do they climb onto other parts of the plant, only last on the flowers.
