Meconema thalassinum is an insect in the family Tettigoniidae known as the oak bush-cricket and drumming katydid.

[1] It is native to Europe, including the British Isles, and was introduced to the United States, first established in the west of Long Island and extending its range to Rhode Island and Scarsdale, Stony Brook, and Ithaca, New York.

Males attract females by making an almost inaudible noise by drumming on leaves .

[4] Meconema thalassinum is a host for the parasitic worm Spinochordodes tellinii.

This is necessary because the parasite requires open water to complete its life cycle.
