Tingis cardui
In 3 days ~10% in a week ~20%
Tingis cardui is a Palearctic lacewing bug. The species is widespread in almost all of Europe and lacking only in the far North. It is common also in North Africa and East Asia minor and the Middle East as well as southern Russia and the Caucasus to Siberia and the North of China.
Tingis cardui lives on Cirsium, in particular on Cirsium vulgare, but also on Cirsium palustre and less frequently on Carduus nutans, Carduus crispus, and Carduus acanthoides. Overwintering occurs as an imago in the ground litter, or under loose bark. The bugs appear in April or May, and sit on the basal leaves of their food crops.
Some make dispersion flights to colonize new plants. Mating and oviposition lasts until July. The females drill their eggs individually on both sides of the leaves into the tissue of the food plant. The nymphs occur from June until September. Older nymphs are often located between the spines on the outside of the flower baskets or close to it. The adult animals of the new generation occur from late July or early August. Wikipedia →

Rare
Under 5% of wildlife watchers report a Spear Thistle Lacebug sighting in Lisbon on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 405th most-seen of the 441 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Spear Thistle Lacebug in Lisbon on a given day, so our monthly data shows no clear season.
Only Lisbon, in our data
Lisbon is the only city on Wallace's Line with enough records to rate Spear Thistle Lacebug sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Spear Thistle Lacebug is recorded against all the insects logged in Lisbon (5 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.
