Beris vallata, the orange legionnaire or common orange legionnaire, is a European species of soldier fly. Beris vallata is a soldier fly, which is black and yellow in colour. The abdomen is entirely yellow, lacking black bands. All tibiae are yellow and then black in the apical half. Wings of the female are yellowish with brown pterostigma, while wings of the male are blackish in colour. Pubescence of the abdomen is black for males and yellow in females. Body length ranges from 5 to 6 mm. The species also possesses six spines which protrude from the back of the scutellum.
The flight period is from may to September. Larvae inhabit moist Bryophyta, where they feed on decaying vegetation. Pupation will take place among fallen decomposing leaves. Adults feed on pollen and nectar including that of Tanacetum vulgare.
Beris vallata is associated with marsh and wet woodland habitats in areas that provide moist conditions for mosses. Larvae can often be found living within mosses in close proximity to bodies of water. Adults are found on vegetation, also in close proximity to moist habitat.

Rare
Under 5% of wildlife watchers report an Orange Legionnaire sighting in London on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 1219th most-seen of the 1504 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 an Orange Legionnaire in London on a given day, so our monthly data shows no clear season.
Among the best
Of the 3 cities where we can rate Orange Legionnaire sightings, London ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Manchester (United Kingdom, under 5%) and Birmingham (United Kingdom, under 5%).
GBIF citizen-science records
It is estimated from how often the Orange Legionnaire is recorded against all the insects logged in London (8 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.
