Black Cherry Aphid (Myzus cerasi). This 3 mm black aphid usually lives in colonies on (ornamental) cherries of the cherry family (Prunus). They live off plant sap. They colonize the tops of the branches, whose leaves begin to curl and become crammed together due to growth retardation.
The eggs are laid in the curled leaves.
Some Prunus species are more susceptible to black cherry aphid colonies than others. For example, the wild cherry – Prunus avium is more prone to be colonised than the Japanese cherryPrunus serrulata
Ants like to “milk” the black cherry aphids.

Where to find

Prevention

Natural enemies include: birds, ladybirds, earwigs, parasitoid wasps and lacewings. Nasturtium (trap crop) captures aphids away; aromatic herbs such as southernwood, lavender and marigolds confuse aphids.
