Classification:
Temnostoma vespiforme belongs to the subfamily Eristalinae, tribe Milesiini.
Distribution:
Palaearctic: From Western Europe to Japan; in Europe from northern Sweden to the Pyrenees and from France to the Caucasus.
Habitat:
Moist deciduous forest with well-developed undergrowth and abundant dead wood.
Description:
Body length 12 - 18 mm; mesoscutum with yellow marks immediately anterior to the postalar calli connected to yellow marks on the postalar calli and elongated yellow marks on each side in the vicinity of the transverse suture, crossing the transverse suture uninterrupted; abdomen: at least tergites 3 - 4 in the male and 3 - 5 in the female with two distinct, transverse, yellow bands frequently joined by a narrow yellow middle strip; the anterior and posterior bands reach the lateral margins of the tergites, which are normally entirely, and broadly, yellow.
Similar species:
A similar species is Temnostoma meridionale. Both species can be distinguished by the yellow spots on the mesoscutum. For comparison, the last picture shows a male of Temnostoma vespiforme and a female of Temnostoma meridionale.
Biology:
Temnostoma vespiforme flies from May to August.
The species is often found near brooks and rivers. The males usually hover at a height of about 3 m. They gather on flowering shrubs and wait for females. Both sexes regularly visit flowers and are often observed on white umbellifers and flowering shrubs (hawthorn, elderberry, raspberry, red honeysuckle).
Larvae of Temnostoma vespiforme live and develop in the wet wood of dead deciduous trees and stumps. The larvae have a stocky, muscular body with hooks in the chest area. They bore burrows in the wood, which they keep open for the supply with oxygen. The wood-eating (xylophagous) larvae feed on microorganisms that live in the wood.
The development of the larvae probably takes 2 years.
Mimicry:
The striking yellow and black colored Temnostoma species not only resemble wasps in their appearance, but also mimic them with their behavior. They usually keep their forelegs extended far beyond the head so that they resemble the antennae of wasps. This mimicry helps to protect against predators, such as birds.
Natural enemies:
Phaenocarpa barthii (Brues, 1907) - Hymenoptera, Braconidae.
Phaenocarpa tiliae Tobias, 1986 - Hymenoptera, Braconidae.
