Diabrotica balteata is a species of cucumber beetle in the family Chrysomelidae known commonly as the banded cucumber beetle. It occurs in the Americas, where its distribution extends from the United States to Colombia and Venezuela in South America. It is also present in Cuba. It is a pest of a variety of agricultural crops.
This beetle is 5 to 6 millimeters long. It has a red head and black thorax. The elytra are yellow, marked with three transverse bands in shades of green or blue-green and a narrower longitudinal green line down the center. The pattern of banding is variable and nearly absent in some individuals. The color of the elytra is influenced by the types of plants the beetle eats. The larva is also variable and has three instars. The new larva is white and about 2.3 millimeters long. It may turn yellow as it consumes plant material. The later-instar larva may reach nearly 9 millimeters.
The adult mates at about six days of age. The female begins producing eggs about 16 days later. She lays a cluster of eggs every few days for two to eight weeks, producing up to 15 clusters, for a maximum of 850 eggs. A cluster has up to 100 oval yellow eggs... Wikipedia →

Rare
Under 5% of wildlife watchers report a Banded Cucumber Beetle sighting in Houston on a given day, based on 75 verified sightings from GBIF citizen-science data. It is the 197th most-seen of the 1057 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.
May and July–September
In those months about 10% of wildlife watchers report a Banded Cucumber Beetle in Houston on a given day, against under 5% in June and October–April, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Banded Cucumber Beetle 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.
5th of 9
Of the 9 cities where we can rate Banded Cucumber Beetle sightings, Houston ranks 5th at under 5%. The best odds are in San Pedro Sula (Honduras, about 10%), Puebla (México, about 10%) and San Luis Potosí (México, about 10%).
GBIF citizen-science records
It is estimated from how often the Banded Cucumber Beetle is recorded against all the insects logged in Houston (75 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.
