Biology
Adults are on wing from June to July in Europe and from June to August in northern North America. They hide amongst low foliage during the day. They become active from dusk onwards. The larvae bore into the stem in the autumn and overwinter in the roots. In the spring they feed on a succession of shoots causing them to wilt. They mainly feed on Achillea species including sneezewort (Achillea ptarmica) and yarrow (Achillea millefolium), but rarely also on tansy (Tanacetum vulgare) and  Tanacetum corymbosum. Similar species
This species is superficially similar to Gillmeria ochrodactyla which has brown and white bands on its hindlegs below the middle spurs, whereas the legs of G pallidactyla are not banded. References
