Caryobruchus gleditsiae is a species of beetle in the family Chrysomelidae (formerly Bruchidae). It lives in North and Central America and develops inside the seeds of palm trees. Adults grow to a maximum length of 11 mm (0.43 in), the size depending on the size of the seed it grew up in. The species was first described by Carl Linnaeus in his 1763 Centuria Insectorum.
Adult beetles are from 4 to 11 millimeters (0.16 to 0.43 in) long, with the body size depending on the size of the seed it grows in as a larva. It is the largest species of Bruchidae in the United States, although other species within the genus can reach 25 mm (0.98 in) long. The adults are black, with short grey hairs and scattered white spots on the elytra.
Caryobruchus gleditsiae is found in the southeastern United States, Mexico, Central America, the West Indies and the Bahamas. A closely related species, Caryobruchus mariae, is found on Cuba. Another closely related species, Caryobruchus maya, is found in southern Mexico, Belize and Guatemala.
While most members of the beetle subfamily Bruchinae (sometimes called the "pea and bean weevils") feed on legumes, Caryobruchus... Wikipedia →

Rare
Under 5% of wildlife watchers report a Palm Seed Weevil sighting in Miami on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 478th most-seen of the 826 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 Palm Seed Weevil in Miami on a given day, so our monthly data shows no clear season.
Yes
Of the 3 cities where we can rate Palm Seed Weevil sightings, Miami has the highest daily chance: under 5%. Next come Austin (United States, under 5%) and Houston (United States, under 5%).
Same family: Chrysomelidae
The closest relatives of the Palm Seed Weevil that you can see in Miami (family Chrysomelidae, Leaf Beetles) are Palmetto Tortoise Beetle (about 10%), Common Sieve Tortoise Beetle (about 10%) and Iridescent Tortoise Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Palm Seed Weevil is recorded against all the insects logged in Miami (12 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.
