Macrosiphum rosae, the rose aphid, is a species of sap-sucking aphids in the subfamily Aphidinae. They have a world-wide distribution and infest rosebushes as the main host in spring and early summer, congregating on the tips of shoots and around new buds. Later in the summer, winged forms move to other rose bushes, or to a limited number of secondary hosts, before returning to rosebushes to lay eggs in the autumn.
Wingless adults have a spindle-shaped body and are between 1.7 and 3.6 mm (0.07 and 0.14 in) long, slender, varying in colour from green to pink and reddish-brown. The antennae and legs are relatively long, and the cauda (tail-like protrusion) is pale. The siphunculi (pair of small backward-pointing tubes on the abdomen) are long, tapered and black, which distinguishes this aphid from Metopolophium dirhodum, the rose-grain aphid, which has pale siphunculi. Winged individuals are between 2.2 and 3.4 mm (0.09 and 0.13 in) in length, varying from green to pinkish-brown, and having distinctive black lateral markings.
This aphid mainly overwinters as eggs on roses, but in mild winters, some adults may survive until spring. The eggs hatch in... Wikipedia →

With luck
About 10% of wildlife watchers report a Rose Aphid sighting in Belgrade on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 74th most-seen of the 127 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
December
In that month about 20% of wildlife watchers report a Rose Aphid in Belgrade on a given day, against under 5% in January–March and June–October, the lowest months.

GBIF citizen-science records
It is estimated from how often the Rose Aphid is recorded against all the insects logged in Belgrade (7 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
