Atherigona reversura
In 3 days ~10%
Atherigona reversura, the bermudagrass stem maggot, is a shoot fly (genus Atherigona) in the family Muscidae. The genus comprises around 300 species, and some of them are very damaging pests in agriculture. The bermudagrass stem maggot takes its name from its host preference for bermudagrass (Cynodon dactylon) and stargrass (Cynodon nlemfuensis).
This small fly has an angular head, transparent wings, and the adult fly is colored between gray and yellow. Males have a rounded abdomen and are smaller than females. The abdomen in the females is larger and pointed. The larvae are cylindrical, white and have mouthhooks that are used to masticate the tender parts of the new shoots.
Atherigona reversura is native to Central and Southeast Asia. This fly was accidentally introduced into Hawaii, and causes great damage in turfgrass. In 2009 it was reported in California and in 2010 was reported in Georgia and southern Mexico. Without clear knowledge of its introduction, the bermudagrass stem maggot has rapidly spread over the Southeastern of United States causing significant yield loss in grazing and hay production systems,

Rare
Under 5% of wildlife watchers report a Bermudagrass Stem Maggot sighting in Houston on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 905th most-seen of the 1057 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Bermudagrass Stem Maggot in Houston on a given day, so our monthly data shows no clear season.
Among the best
Of the 2 cities where we can rate Bermudagrass Stem Maggot sightings, Houston ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Washington (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Bermudagrass Stem Maggot is recorded against all the insects logged in Houston (7 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.
