Several of these agromyzid flies sit on the blossoms of Aquilegia vulgaris - Phytomyza aquilegiae? Any other similar species known to be associated with that plant?

There are three agromyzids associated with Aquilegia - Ophiomyia aquilegiana which mines stems, Phytomyza aquilegiae which produces blotch mines in leaves and Phytomyza miniscula which makes an irregular linear mine. I suspect yours is P. aquilegiae, but I can't see all the detail to be sure. Best to look out for mines in a few weeks' time. Tony ---------- Tony Irwin |

Phytomyza krygeri develops in the seeds of Aquilegia (quite unusual habitat for Agromyzidae). Association of the female with Aguilegia flower may indicate this species. However, I am not a specialist capable of confirming it. |

Does this additional photo help to exclude one of the candidates?
