The milkweed leaf beetle, or swamp milkweed leaf beetle (Labidomera clivicollis) is a species of leaf beetle from the family Chrysomelidae. It is found in eastern Northern America. These leaf beetles are round bodied, 8–11 mm in length, with a black head and pronotum and bright orange to yellow elytra with variable mottled black patches. L. clivicollis somewhat resembles a large ladybird beetle, and though it is not in the ladybird family (Coccinellidae), it is closely related (infraorder Cucujiformia). The larvae are light orange, white, or gray with a black pronotum and prominent black spots on the spiracles. They are grub-like and can be found feeding on milkweeds, especially swamp milkweed. Milkweed leaf beetle larvae can be distinguished from visually similar and closely related species by color, host plant, and number of spots.
There are a number of L. clivicollis host plants which are toxic to most herbivores. Many are in the dogbane family (Apocynaceae) including milkweeds, especially swamp milkweed (Asclepias incarnata) and common milkweed (Asclepias syriaca); swallow-wort (Cynanchum); twinevine (Funastrum).

Rare
Under 5% of wildlife watchers report a Swamp Milkweed Leaf Beetle sighting in Monterrey on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 209th most-seen of the 413 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.
September to November
In those months about 10% of wildlife watchers report a Swamp Milkweed Leaf Beetle in Monterrey on a given day, against under 5% in December to August, the lowest months. Those are among Monterrey's wettest months, with about 95 mm of rain a month against 20 mm in February.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Swamp Milkweed Leaf Beetle sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
11th of 15
Of the 15 cities where we can rate Swamp Milkweed Leaf Beetle sightings, Monterrey ranks 11th at under 5%. The best odds are in Montreal (Canada, about 10%), Minneapolis [Saint Paul] (United States, about 10%) and Detroit (United States, about 10%).
Same family: Chrysomelidae

GBIF citizen-science records
It is estimated from how often the Swamp Milkweed Leaf Beetle is recorded against all the insects logged in Monterrey (13 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.
