The larva of Phytomyza krygeri feeds in the seed capsules of Aquilegia vulgaris (Columbine). Pupation occurs in the seed head, with one puparium occurring in each seed capsule. The affected seed capsules discolour and become brown (as shown below). The larva is bright yellow and during development may leave one seed capsule and enter another, seen by congruent holes in adjacent seed capsules. The puparium is deep brown with all segments having a row of stout spinules, which are most prominent in the anal region.

See the National Agromyzidae Recording Scheme webpage for this species for further details of puparium and adult insect.
