< back

 

Food Plant: Aquilegia vulgaris (Columbine)

Egg: on the petals

Mine: March-June

Notes: The larva feeds in the seed capsules and pupariation occurs in the seed head, with one puparium occuring in each seed capsule. The larva is bright yellow and during development may leave one seed capsule and enter another, seen by congruent holes in adjacent seed capsules (as shown). The affected seed capsules discolour and become brown (as shown). The puparium is deep brown with all segments having a row of stout spinules, which are most prominent in the anal region. The posterior spiracles are strongly chitinised.
