Maruca vitrata
In 3 days ~10% in a week ~30%
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...

Rare
Under 5% of wildlife watchers report a Mung Bean Moth sighting in Beijing on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 162nd most-seen of the 401 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
August and September
In those months about 10% of wildlife watchers report a Mung Bean Moth in Beijing on a given day, against under 5% in October to July, the lowest months. Those are among Beijing's wettest months, with about 85 mm of rain a month against almost none 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.
25th of 30
Of the 30 cities where we can rate Mung Bean Moth sightings, Beijing ranks 25th at under 5%. The best odds are in Vijayawada (India, about 30%), Kathmandu (Nepal, about 20%) and Vadodara (India, about 20%).
Same family: Crambidae
The closest relatives of the Mung Bean Moth that you can see in Beijing (family Crambidae, Crambid Snout Moths) are Hawaiian Beet Webworm Moth (about 10%), Box Tree Moth (about 10%) and Rush Veneer (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 Beijing (16 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.
