| | | | Common Sawflies - Tenthredinidae | | The Common Sawflies (Tenthredinidae) are a family of wasps in the order Hymenoptera, the suborder sawflies (Symphyta) and the superfamily Tenthredinoidea. There are 6500 - 9000 species worldwide, 1070 species and subspecies of which can be found in Europe. In Central Europe there are approximately 850 species. | | |
| | | | Adult Tenthredinidae reach body lengths of 2 - 20 mm and are usually black or brown in colour although their appearance and colouration can vary widely. There are many species which are bright green, red or yellow in colour and with various patterns which create a partial resemblance to Vespidae (wasps), but Tenthredinidae are not able to sting. The so-called "wasp waist" is absent. Their antennae can have 7 - 15 segments, but mostly have 9 segments. | | |
| | | | Their bodies are elongated. The abdomen has 9 segments. The females have a short ovipositor, shaped like a saw. The females cut into plants and lay their eggs with the ovipositor. The larvae of some species live in leaf courses, while others live in galls. | | |
| | | The larvae resemble caterpillars. They have segmented legs attached to the chest and 6 to 8 pairs of hind legs. They have two simple eyes. The larvae feed on the leaves or the fruit of various trees, shrubs and herbaceous plants. They often appear in groups on leaves which they eat from outside in. They often “ride” on the leaves’edges while eating and - raise up their abdomen when disturbed. | | |
| | | After 5 to 6 moults, the larvae of Tenthredinidae spin a cocoon in leaf litter or directly in the ground in which they remain, sometimes even for years, resting before they pupate. Adult Tenthredinidae have lifespans of only a few days or a few weeks. Tenthredinidae include some species that are economically important plant pests. | | |
