Trypeta artemisia mine

Artemisia vulgaris, Hilversum: a very young mine (lighted from behind), in which the oviposition scar still can be recognised (arrow

mine

The mine begins as en elongated blotch overlying a strong vein; from there broad tunnels radiate that coalesce in the end. All frass is concentrated at a central point in the floor of the mine. As a result the mine has a brownish-black centre and a paler brownish green seam. The larva often (perhaps always at daylight) rests in the centre of the mine. Primary and secondary feeding lines as a rule quite clear. Pupation outside the mine.

hostplants

Asteraceae, oligophagous

Achillea biserrata, ptarmica; Artemisia absinthium, gnaphalioides, moxa, vulgaris; Chrysanthemum indicum; Eupatorium cannabinum; Senecio nemorensis; Tanacetum corymbosum, macrophyllum, parthenium, vulgare.

phenology

Larvae from June till September (Hering, 1957a).

BENELUX

BE recorded (Leclercq & De Bruyn, 1991a).

NE recorded (de Meijere, 1939a; van Aartsen & Smit, 2002).

LUX recorded (Ellis, Hobscheid).

distribution within Europe

All of Europe west of Vienna; also Bulgary, therefore the range probably covers a much larger area (Fauna Europaea, 2008).

notes

Very common; not infrequently all leaves of a plant are infested, and many leaf segments of each individual leaf. Despite the ubiquicity of the mines adult flies are captured only rarely (Kabos & van Aartsen, 1984a; Wakkie, 1994a). In the past a pest on Chrysanthemum.

Sometimes, especially on Tanacetum, the mines may be unusually large. For a number of years I have assumed that these were mines of T. zoe, but the constant absence of a narrow initial corridor has convinced me that these too are mines of artemisiae.
