Chaetorellia jaceae is a fly from the family of bored flies (Tephritidae).
features
The drill flies are about 4 mm long. Their body is colored ocher-yellow. Two rows of black spots run over the pronotum and the abdomen . There are also two black lines on each side of the pronotum and a dark spot at the apical end of the label . The compound eyes shimmer green. The wings are predominantly colored light brown. Three transparent strips lead forward from the rear edge of the wings. The relatively small holders are cream-colored. The back of the head and pronotum have bristle hairs. The abdomen is also hairy. The females have a red-brown ovipositor at the end of the abdomen .
distribution
Chaetorellia jaceae is widespread in Europe. Their occurrence ranges from the Mediterranean region in the south to England and Scandinavia in the north. In the east, the occurrence extends to the Middle East .
Way of life
The Bohrfliegenart uses as host plants different knapweed , including the Meadow knapweed ( Centaurea jacea ), the Centaurea nigra ( Centaurea nigra ), Centaurea debeauxii and the Greater Knapweed ( Centaurea scabiosa ). In addition, the common thistle ( Cirsium vulgare ) is considered to be a host plant for bored flies. The larvae develop in the flower heads of their host plants. The bored flies can be seen from June to August. They are flower visitors of umbellifers like the Berg-Haarstrang . The species forms 1–2 generations per year. The overwintering generation pupates in autumn.
