Chrysoperla carnea, one of the species of common green lacewing, is an insect in the Chrysopidae family. Although the adults feed on nectar, pollen and aphid honeydew, the larvae are active predators and feed on aphids and other small insects. It has been used in the biological control of insect pests on crops.
Chrysoperla carnea was originally considered to be a single species with a holarctic distribution but it has now been shown to be a complex of many cryptic, sibling subspecies. These are indistinguishable from each other morphologically but can be recognised by variations in the vibrational songs the insects use to communicate with each other, which they especially do during courtship.
The green lacewing eggs are oval and secured to the plant by long slender stalks. They are pale green when first laid but become gray later. The larvae are about one millimetre long when they first hatch. They are light brown to cream coloured, often with markings, and have been compared in appearance to small alligators, crawling actively around in search of prey. They have a pair of pincer-like mandibles on their head with which they grasp their prey, sometimes lifting the victim... Wikipedia →

Rare
Under 5% of wildlife watchers report a Chrysoperla carnea sighting in Kyiv on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 477th most-seen of the 753 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
March–April, October and December
In those months about 10% of wildlife watchers report a Chrysoperla carnea in Kyiv on a given day, against under 5% in January–February, May–September and November, the lowest months.
Yes
Of the 4 cities where we can rate Chrysoperla carnea sightings, Kyiv has the highest daily chance: under 5%. Next come Warsaw (Poland, under 5%) and Paris (France, under 5%).
GBIF citizen-science records
It is estimated from how often the Chrysoperla carnea is recorded against all the insects logged in Kyiv (9 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.
