gall

Aphids on the roots. They are attended by ants both on the primary and on the secondary host plant.

Based on the secondary host plant, three subspecies are recognised. D. crataegi crataegi migrates to Daucus carota, less frequently also Anthriscus and Myrrhis. D. c. aethusae (Börner, 1950) migrates to Aethusa ad Torilis. D. c. kunzei (Börner, 1950) migrates to Pastinaca.

secondary host plants

Apiaceae, oligophagous

Aethusa cynapium; Anthriscus sylvestris; Chaerophyllum temulum; Daucus carota; Heracleum sphondylium; Myrrhis odorata; Pastinaca sativa; Peucedanum alsaticum; Torilis arvensis subsp. neglecta, japonica.

The reference to Aegopodium podagraria by Buhr is probably erroneous. Barbagallo ao report observations in Italy on Chaerophyllum and Heracleum without attributing them to a specific subspecies.

synonyms

Jezabura, Yezabura crataegi.

The subspecies D. c. aegopodii (Börner, 1950) and D. c. anthrisci (Börner, 1950) are synonymous with the typical form.
