The larva is a "false-caterpillar" which feed on the young fruit.

Reproduction is usually parthenogenetic. The yellow prune tree sawfly (Hoplocampa flava) is very common.^[3]

Treatments

At the start of vegetation (10 to 15 days before flowering), install white glued bands on the trees at a height of about 0.70 to 1 meter. When the adults get active, they mistake them for flowers and get stuck on them.

Idem for the cherry sawfly but with yellow bands.
