This species is ubiquitous in low-temperature diffuse flow, being found on bare rock, sulphides, Kiwa sp.,
gastropods Gigantopelta chessoia, and stalked barnacles.
On the carapace of Kiwa n. sp.,
a "halo" of pale colouration surrounding the limpets indicates where this species of Lepetodrilus is grazing epizoic microbes.

The population density of Lepetodrilus sp.
on the barnacles Vulcanolepas scotiaensis was estimated to 20,172–56,904 individuals m⁻².
