In 3 days ~50% in a week ~80%
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...

Possible
About 20% of wildlife watchers report a Mung Bean Moth sighting in Ranomafana National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 32nd most-seen of the 68 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
May
In that month about 50% of wildlife watchers report a Mung Bean Moth in Ranomafana National Park on a given day, against under 5% in June, August–September and November–April, the lowest months. That is one of Ranomafana National Park's driest months, with about 120 mm of rain against 450 mm in January.
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.
4th of 20
Of the 20 parks where we can rate Mung Bean Moth sightings, Ranomafana National Park ranks 4th at about 20%. 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 Ranomafana National Park (family Crambidae, Crambid Snout Moths) are Orphnophanes ankarampotsyalis (about 30%), Euphyciodes albotessulalis (about 20%) and Glyphodes toulgoetalis (about 20%), 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 Ranomafana 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.
