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 Arenal Volcano National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 152nd most-seen of the 302 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Mung Bean Moth is recorded against all the insects logged in Arenal Volcano National Park (9 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.
