Boinka is listed within the Victorian Flora and Fauna Guarantee Act 1988 as being one of only two places where Pale Myoporum (Myoporum brevipes Benth.), a recumbent or erect shrub of up to 2 metres in height (widespread in South Australia), is known to grow indigenously outside of that location.
Its native habitat is very arid, cover is sparse, and consists of saltbush and other chenopods and emu bush.
Adults and juveniles feed off plants including certain Coprosma, Griselinia and Myoporum species.
Heliocybe sulcata typically fruits on decorticated, sun-dried and cracked wood, such as fence posts and rails, vineyard trellises in Europe, branches in slash areas, and semi-arid areas such on sagebrush or on naio branches in rain shadow areas of Hawaii, or in open pine forests.
The weevil is known to live on Ngaio trees (Myoporum laetum), feeding on leaves, where it produces a characteristic feeding notch.
