The Indianmeal moth (Plodia interpunctella), also spelled Indian meal moth and Indian-meal moth, is a pyraloid moth of the family Pyralidae. Alternative common names are weevil moth, pantry moth, flour moth or grain moth. The almond moth (Cadra cautella) and the raisin moth (Cadra figulilella) are commonly confused with the Indianmeal moth due to similar food sources and appearance. The species was named for feeding on Indian meal (the cornmeal and maize flour from maize), with Indian in the New World sense; it does not occur natively in India. It is also not to be confused with the Mediterranean flour moth (Ephestia kuehniella), another common pest of stored grains.
P. interpunctella larvae (caterpillars) are commonly known as waxworms. They are not the same species as the waxworms often bred as animal feed. Rather, they are a common grain-feeding pest found around the world, consuming cereals, fruits, and similar products. Substantial efforts have been taken in the United States to control the moth's damage to grain crops.
The larvae of this species have the ability to bite through plastic and cardboard so even sealed containers may be infested. Once found, the moths are difficult to eradicate. The last larval instar is also able to travel long distances before pupating; so a new infestation site may develop far from the last pupation site. In addition to food sources, this species can reproduce and pupate on clothing and any source of clothing must be inspected to prevent reinfestation. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Indian-Meal Moth is recorded against all the insects logged in João Pessoa (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.
