Lixus pulverulentus is a species of weevil belonging to the family Curculionidae. It is commonly known as the elongated bean weevil. The species was scientifically described in 1763 by Giovanni Antonio Scopoli as Curculio pulverulentus Scopoli, 1763.
This widespread, but quite rare species can be found in southern and central Europe (including the Iberian Peninsula), from Iran to Asia Minor and in the Mediterranean Basin, including North Africa and the Middle East Hastings Country Park produced the last British records of this species and it is now considered to no longer breed in Britain.
Lixus pulverulentus can reach a body length of about 10.5–17.5 mm (0.41–0.69 in). These rather long weevils have a narrow, elongated body. The conically shaped pronotum is hardly granular. They are dusted yellowish to brownish.
The beetles appear in April. They are mainly seen in May and June. Larvae of these polyphagous beetles mainly develop in the stems of Malvaceae, Asteraceae, and Fabaceae (Alcea rosea, Malva pusilla, Malva sylvestris. Malva thuringiaca.Cirsium arvense, Cirsium palustre, Cirsium serrulatum, Carduus acanthoides, Silybum marianum... Wikipedia →

Rare
Under 5% of wildlife watchers report an Elongated Bean Weevil sighting in Lyon on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 318th most-seen of the 411 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.
April to June
In those months about 10% of wildlife watchers report an Elongated Bean Weevil in Lyon on a given day, against under 5% in July to March, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Elongated Bean Weevil sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
10th of 13
Of the 13 cities where we can rate Elongated Bean Weevil sightings, Lyon ranks 10th at under 5%. The best odds are in Izmir (Turkey, about 30%), Algiers (Algeria, about 20%) and Athens (Greece, about 10%).

GBIF citizen-science records
It is estimated from how often the Elongated Bean Weevil is recorded against all the insects logged in Lyon (10 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.
