Hoplocampa plagiata (Klug, 1816)
on Amelanchier, Sorbus
Larvae bore in the unripe fruits.
“Affected fruit is easily detected, because of the hole made basally in its side, through which the larva ejects its excreta and cast skins. Although not every plant of A. ovalis harboured the sawfly, in those that were infested, one or two larvae were found in each cluster of fruit.” (Liston, 2007b)
