Mecodema crenicolle is a species of ground beetle endemic to New Zealand. It is found only on the North Island of New Zealand where it occurs in native forest, pine plantation and pasture habitats. As an adult, it is a medium-large beetle with a length of 22–29 mm. It is black with distinctive puncture marks over much of its body and is similar to Mecodema venator, its sister species. It was first described in taxonomic literature by French naturalist François-Louis Laporte de Castelnau in 1867. Like other Mecodema, it is flightless and a predator of invertebrates.
This species was first described in modern taxonomic literature by French naturalist François-Louis Laporte de Castelnau in 1867 from a specimen collected in the Auckland region. The holotype (a single specimen on which the species description is based) is stored in the Natural History Museum, Vienna. The species was unknowingly described again under four additional names: Mecodema crenaticolle by Austrian entomologist Ludwig Redtenbacher in 1868, then as Mecodema rugicolle, Mecodema lineatum and Mecomedema variolosum by Scottish entomologist Thomas Broun in 1882, 1894 and 1903 respectively.

Possible
About 20% of wildlife watchers report a Mecodema crenicolle sighting in Abel Tasman National Park on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 12th most-seen of the 64 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
October
In that month about 30% of wildlife watchers report a Mecodema crenicolle in Abel Tasman National Park on a given day, against under 5% in February, May and July–September, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Mecodema crenicolle sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 parks where we can rate Mecodema crenicolle sightings, Abel Tasman National Park has the highest daily chance: about 20%. Next come Egmont National Park (New Zealand, about 10%).
Same genus: Mecodema
The closest relatives of the Mecodema crenicolle that you can see in Abel Tasman National Park (genus Mecodema) are Mecodema strictum (about 10%) and Mecodema costellum (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Mecodema crenicolle is recorded against all the insects logged in Abel Tasman National Park (15 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.
