Columbine Leaf Miner

Phytomyza aquilegiae is a fly whose larvae mine the leaves of Columbine ( Aquilegia vulgaris ) and some related species. The mine is a large blotch on the upper surface of the leaf, sometimes occupied by several larvae. Frass is scattered throughout the mine. The mine is often purple-brown and without a preceding corridor. Leaves can sometimes be largely destroyed by the size of the mine. See the National Agromyzidae Recording Scheme webpage for this species for further details of puparium and adult insect. ref.: Warrington, B.P. (2023). Phytomyza aquilegiae .
