Plant Parasites of Europe

leafminers, galls and fungi

Procas granulicollis

Procas granulicollis Walton, 1848

climbing corydalis weevil

parasite

The biology of the few Procas species is unknown. Only in P. granulicollis it has been observed that the weevils, straddling a leaf, were eating Ceratocapnos claviculata; in captivity they also accepted Pseudofumaria lutea. However, it is considered impossible that these plants could be the larval host plants. The most likely candidate is Pteridium aquilinum, but despite much efforts this has not been confirmed.
