Prays fraxinella

Prays fraxinella (Bjerkander, 1784)

ash-bud moth

Prays fraxinella mines

Fraxinus excelsior, Bunderbos

Prays fraxinella mine


egg shell


In late autumn the larvae make an irregular small corridor with dispersed black frass. Often the corridor widens in the end into an irregular blotch with much less frass. The mine may begin at an egg shell (lower picture), but the larvae can leave their mine and start a new one elsewhere in the leaf; in that case the corridor begins with a small round opening. Before the leaf is shed the larva leaves the mine and bores into the bark, where it hibernates. After hibernation they live as shoot borer, of free among spun leaves

host plants

Oleaceae, oligophagous (?)

Fraxinus excelsior, ornus.

The species is also reported from Daphne, but is is not really clear whether this concerns a regular relationship.
