Sitona lineatus, the pea and bean weevil or pea leaf weevil, is a species of weevil with a Palearctic distribution. It is a common pest of beans, peas, and other plants in the family Fabaceae. Adult S. lineatus beetles measure 3.4–5.3 mm (0.13–0.21 in) in length. They are characterized by a series of colored scales arranged in alternating lines (striae) on the elytra; it is from this characteristic where the species gets its name lineatus meaning 'lined' or 'striped'. The head and pronotum also have fine pointed setae amongst the scales. The antennae are clubbed, pointed and preceded by 7 segments. The femora is dark, but tibiae and tarsi are red. As a member of Order Coleoptera (beetles) their forewings are modified to form hardened covers over the thorax and abdomen, with the hindwings for flight underneath.
Sitona lineatus is native to Europe and North Africa, and is considered an invasive species in North America. In North America, they are typically found in the western prairie provinces of Canada (Alberta, Saskatchewan, Manitoba), from where they show expansion toward the Canada/USA border into North Dakota, and north into higher latitudes of Alberta.

Rare
Under 5% of wildlife watchers report a Pea Weevil sighting in Wadden Sea National Park on a given day, based on 13 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 408th most-seen of the 818 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–May, August and November
In those months about 10% of wildlife watchers report a Pea Weevil in Wadden Sea National Park on a given day, against under 5% in June–July, September–October and December–March, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Pea Weevil sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Wadden Sea National Park, in our data
Wadden Sea National Park is the only park on Wallace's Line with enough records to rate Pea Weevil sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Pea Weevil is recorded against all the insects logged in Wadden Sea National Park (13 verified sightings from 2019 to 2026), 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.
