Bucculatrix fatigatella von Heyden, 1863
mine
The larva initially makes a very narrow corridor, often closely following the leaf margin, with a proportionally broad, continuous frass line. After a while the larva vacates the mine, and starts to live free on the leaf. At the end of the corridor remains a relatively long frass-free larval chamber. The free larva makes a considerable number of small round fleck mines.
host plants
Asteraceae, narrowly oligophagous
Achillea millefolium; Artemisia alpina, campestris, umbelliformis.
According to Burmann (1991a) does the species live strictly monophagous on Achillea millefolium; the material from Artemisia would belong to an undescribed species. Hering (1957a) mentions fatigatella also from Leontopodium, but the description he gives of the mine does not fit this this species.
phenology
Larvae in June (Hering, 1957a).
BENELUX
