Upper Midwest Stem Insect Survey

Stem borer (Diptera: Agromyzidae) in Angelica

Record Details

[?] Top
Record no.:0061
Feeding guild:Stem borer
Taxonomy:Diptera: Agromyzidae: Melanagromyza angelicae
Stages observed:trace, puparium, adult
Hosts in Angelica:A. atropurpurea (angelica)

I noted larval tunnels winding through the layer of whitish tissue lining the interior of a hollow stem of the host. Puparia were formed in these stem tunnels, and the wide separation distance of the puparium's posterior spiracular plates (about twice their diameter) along with their central horns fit well with the description of Melanagromyza angelicae in Spencer and Steyskal (1986). I successfully overwintered puparia, and one or more adults emerged the following spring; O. Lonsdale identified them to species (Eiseman 2023, Eiseman et al. 2026).
