Meloe americanus is a type of blister beetle (Meloidae) found in North America. It is most relevant to the fields of agriculture and veterinary medicine. Adult beetles feed on different types of plants, which cause crop damage. They also release a fluid containing a chemical that is toxic, and at high concentrations lethal, to mammals. The first instar larvae are uniquely active and mobile, utilizing phoresy and parasitism to feed and mature through their developmental stages.

They are called “oil beetles” because of a fluid they release from their joints when they feel threatened. Adult body length ranges from 7 mm to 17 mm [8].

The elytra are short and abbreviated, while the hind wings are not present. Therefore, M. americanus are unable to fly as adults. Both females and males have similar... Wikipedia →

Rare
Under 5% of wildlife watchers report a Buttercup Oil Beetle sighting in Dallas on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 1213th most-seen of the 1412 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Buttercup Oil Beetle in Dallas on a given day, so our monthly data shows no clear season.
Among the best
Of the 2 cities where we can rate Buttercup Oil Beetle sightings, Dallas ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Austin (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Buttercup Oil Beetle is recorded against all the insects logged in Dallas (6 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.
