CHECKLIST OF ICHNEUMONIDAE (HYMENOPTERA) OF POLAND
Ichneumonidae occur in all continents. They inhabit mainly terrestrial habitats but aquatic species are also known. Body size of imagines varies from 3 to 35 mm, and together with ovipositor it reaches to 165 mm. Long, straight antennae almost always consist of more than 16 segments. In the composition of thorax there is an additional intermediate segment (propodeum), originated as a result of uniting metathorax and the first segment of abdomen. The intermediate segment is divided by carinae into many areas. On both sides of the first tergite, before a spiracle, there occur longitudinal depressions - glymmae. Connection
between the second and third tergites of the abdomen is flexile. Trochanters are usually double and middle tibia are provided with two calcars (rarely one). Wing stigma is well-marked. In most of species the fore-wing has second recurrent vein; areolet may also occur. Rarely, wings are completely lacking or reduced.
