...st (thorax) is shiny black. Their scutellum is also light yellow. They have markings on the upper surface. The females have an ovipositor on the end of their bodies.
The adult flies have a life span of about 1 week and only feed on vegetables (phytophagous). Aside from the open air, they are mainly encountered in greenhouses. After hatching from pupae, the females start feeding immediately. They drill small holes in the top surface of plants’ leaves using their ovipositors and suck up liquid with their mouth parts. The damaged areas on the leaf tissue (which also enable bacteria and fungi to penetrate into the plant) are clearly visible as yellowish stains.

| | Beetles | | ...ate from about 265 million years ago.
Beetles’ bodies are significantly different to other insects’ in that they do not solely comprise head, chest and abdomen. The second section consists solely of the prothorax, of which only the neck shield on top of the body is evident. The remaining two sections of the chest, together with the abdomen, form one unit, which is overlaid by the first pair of wings (the cover wings).
Beetles can vary enormously in size ranging from 170 mm in length (Titan be... | | |
| | Forest bug | | ...atomidae. It is one of the biggest bugs in Central Europe and can reach a length of 13 to 15 mm. In the summer, it is bronze coloured, in the autumn, dark brown in colour. The upper edges of the pronotum are strongly curved. The neck shield at the top lights in orange. The proboscis is very long. The legs and the first set of antennae are maroon coloured. The larvae of forest bugs are dark. With age they become lighter in colour, especially their abdomens. | | |
| | Forest bug feed by sucking out the insides of fruit. They occasionally kill other insects and suck dead other arthropods (insects, arachnids, crustaceans etc). After mating, the females lay their eggs on top of a leaf. The larvae overwinter - unlike those of other kinds of shield bugs - under the bark of trees, and their further development takes place on broad-leaved trees. | | |
