die out
Mecodema punctellum was discovered in 1916 and was last detected in 1931. After searches failed in 1961, 1971, 1974 to 1976, 1981, 1990, 1996 on Stephens Island and 1997 on D'Urville Island , it is now considered extinct. The reason for its disappearance is believed to be habitat destruction, as large, rotten tree trunks are no longer present on Stephens Island.
