Monoecious holocyclic with apterous males.

Rosa spp., rose trees, Dasiphora, cinquefoils, potentillas

M. rosarum colonizes both wild and cultivated rose bushes and trees, more particularly lclimbing rose varieties and potentillas. This small species is difficult to spot. The larvae hide in leaflets that are not yet opened out. They feed on the veins of both sides of the leaves. M. rosarum can be noticed if it produces intense proliferations, which is rare. The alates appear in summer. The oviparae and small apterous males appear in autumn. This species is not particularly harmful.
