Naupactus leucoloma is a species of broad-nosed weevil in the beetle family Curculionidae. The adult of Naupactus leucoloma is dark grey in colour with two lighter-coloured bands running longitudinally down its thorax and head. They are between 8-12mm long, and 4mm wide at the abdomen. The body of N. leucoloma is covered with hairs that are longer on the forewing. Wings of N. leucoloma vary greatly in size between individual specimens, but the forewings are fused, thus making the adults unable to fly. Males are not known to exist with N. leucoloma outside of their native range, and all individuals are females in the naturalised range. Reproduction is through parthenogenesis. Males of N. leucoloma are rare and only occur in the native range of South America, but also may be extinct.
The larvae of N. leucoloma are about 12mm long, and occur in the soil. They have no legs similar to other species of weevils, their heads are partially retracted into the thorax, and they are yellowish white in colour, with black mandibles protruding from the head.
Naupactus leucoloma is native to much of Argentina, from the Jujay and Salta provinces northwest, right down... Wikipedia →

With luck
About 10% of wildlife watchers report a White-Fringed Weevil sighting in Melbourne on a given day, based on 96 verified sightings from GBIF citizen-science data. It is the 153rd most-seen of the 875 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
January to April
In those months about 10% of wildlife watchers report a White-Fringed Weevil in Melbourne on a given day, against under 5% in May to December, the lowest months.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most White-Fringed 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.
Among the best
Of the 13 cities where we can rate White-Fringed Weevil sightings, Melbourne ranks 5th at about 10%, level with the leaders once rounded. The best odds are in Hobart (Australia, about 10%), Auckland (New Zealand, about 10%) and Santiago (Chile, about 10%).
GBIF citizen-science records
It is estimated from how often the White-Fringed Weevil is recorded against all the insects logged in Melbourne (96 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.
