| | | Tachina flies | | Tachina flies (Tachinidae), also called tachinids, are a family in the order Diptera. Approximately 8200 species are encountered throughout the world. About 500, are found in Europe. The tachina flies are divided into 4 subfamilies, known as Phasiinae, Dexiinae, Tachininae and Exoristinae. | | |
| | | | These predominantly diurnal flies reach body lengths of 2-20 mm, with the length varying according to what species they are. They are primarily black in colour with grey tires. They are often very hairy, especially their abdomens. Tachina flies can be identified by their scutellum. This bulges at the rear edge of the upper side of the chest - just like a bead segment. Their sensors are tripartite. At the front of their heads there are sucking (sometimes piercing and sucking) mouth parts. | | |
| | Adult tachina flies feed on honeydew, nectar, vegetable juices, feces or on carrion. Their larvae feed parasitically on all kinds of larvae, pupae and adult insects. This includes caterpillars, beetles (larvae and adults) and the larvae of various Diptera and arthropods. The larvae of the tachina flies enter their host animals in different ways. Firstly through ingestion of their eggs, secondly through oviposition directly on the host animal, or thirdly through the hatched larvae’s direct entry into the host animal. Usually the host animals die before the larvae’s development is complete. The pupation of the larvae usually occurs outside the host animal.
Since the larvae of many tachina flies kill pests, they are very welcome in the agriculture and forestry industry. | | |
