Micrurus diastema, commonly known as the diastema coral snake, the variable coral snake, and coral diastema in Spanish, is a species of venomous snake in the family Elapidae. The species is native to southeastern Mexico and northern Central America. There are seven recognized subspecies.
Micrurus diastema occurs in Belize, Guatemala, Honduras, and southeastern Mexico. The preferred natural habitat of Micrurus diastema is tropical wet, moist, and dry forest from near sea level to 1,250 m (4,100 ft), but it tolerates habitat disturbance and is also found in agricultural areas.
Micrurus diastema is terrestrial. Micrurus diastema is oviparous. There are seven subspecies which are recognized as being valid, including the nominotypical subspecies. Micrurus diastema affinis (Jan, 1858) Micrurus diastema aglaeope (Cope, 1860)
Micrurus diastema alienus (F. Werner, 1903) Micrurus diastema apiatus (Jan, 1858) Micrurus diastema diastema (A.M.C. Duméril, Bibron & A.H.A. Duméril, 1854) Micrurus diastema macdougalli Roze, 1967 Micrurus diastema sapperi (F. Werner, 1903)

No species of the same family or order lives in Montes Azules Biosphere Reserve, so these are its closest relatives here: other reptiles.
Possible
About 20% of wildlife watchers report a Variable Coralsnake sighting in Montes Azules Biosphere Reserve on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 5th most-seen of the 6 reptiles we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
June
In that month about 40% of wildlife watchers report a Variable Coralsnake in Montes Azules Biosphere Reserve on a given day, against under 5% in January, March–May, July and October–November, the lowest months. That is one of Montes Azules Biosphere Reserve's wettest months, with about 370 mm of rain against 55 mm in March.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Variable Coralsnake sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 parks where we can rate Variable Coralsnake sightings, Montes Azules Biosphere Reserve has the highest daily chance: about 20%. Next come Cerro Azul Meámbar National Park (Honduras, about 20%) and Calakmul Biosphere Reserve (Mexico, about 10%).
GBIF citizen-science records
It is estimated from how often the Variable Coralsnake is recorded against all the reptiles logged in Montes Azules Biosphere Reserve (5 verified sightings from 2019 to 2026), 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.
