Maruca vitrata is a pantropical insect pest of leguminous crops like pigeon pea, cowpea, mung bean and soybean. Its common names include the maruca pod borer, bean pod borer, soybean pod borer, mung moth, and the legume pod borer. The species was first described by Johan Christian Fabricius in 1787.
It can cause losses of 20–80% on the harvests of cowpeas. Its feeding sites on plants are flower buds, flowers and young pods. In some cases early instars feed on flower peduncles and young stems. Some parasitoids have been shown to serve as a biological control for Maruca vitrata. Parasitoid wasps families include Braconidae and Ichneumonidae; some parasitoid flies in the Tachinidae are also natural enemies of the moth. M. vitrata prefers to lay its eggs on the flowering bodies of the cowpea plant. Efforts have been made to deter M. vitrata from reproducing on the plant ranging from pesticides to a chemical specifically designed to sterilize the moth. Genetically modified cowpeas has been developed to express the cry protein from Bacillus thuringiensis, which is toxic to lepidopteran species, particularly to the pod borer. This technology have...

With luck
About 10% of wildlife watchers report a Mung Bean Moth sighting in Manu National Park on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 95th most-seen of the 366 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
January and May
In those months about 20% of wildlife watchers report a Mung Bean Moth in Manu National Park on a given day, against under 5% in April and October–December, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Mung Bean Moth sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
12th of 20
Of the 20 parks where we can rate Mung Bean Moth sightings, Manu National Park ranks 12th at about 10%. The best odds are in Brownsberg Nature Park (Suriname, about 40%), Gorongosa National Park (Mozambique, about 30%) and Kanha National Park (India, about 20%). All parks ranked.
Same family: Crambidae
The closest relatives of the Mung Bean Moth that you can see in Manu National Park (family Crambidae, Crambid Snout Moths) are Siga liris (about 20%), Red-Spotted Sweetpotato Moth (about 10%) and Polygrammodes multifenestrata (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Mung Bean Moth is recorded against all the insects logged in Manu National Park (15 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.
