Aulagromyza luteoscutellata

Leaf-mining fly Aulagromyza luteoscutellata

Description

Aulagromyza luteoscutellata is a leaf-mining fly from the family Agromyzidae, primarily attacking plants of the honeysuckle family (Caprifoliaceae). The larvae create characteristic mines on the leaves of their host plants. This species is oligophagous, with a preference for Lonicera xylosteum, but it can also develop on Lonicera periclymenum, Lonicera tatarica, Leycesteria formosa, and Symphoricarpos albus. The mining activity leads to the formation of linear, upper-surface corridors filled with dark green frass in a wide band. Pupation occurs outside the mine.

The species is distributed across Europe, where it is commonly found in woodlands, hedgerows, and urban greenery. While infestations do not typically threaten plant health, heavy attacks can reduce photosynthetic efficiency and impact the aesthetic appearance of the host plants.

Symptom

The larvae form narrow, slightly widening leaf mines that do not follow the leaf margin. The frass is deposited in a continuous dark green band with scattered granules. The mines remain unbranched, and pupation occurs externally.
