The young larva penetrates the top of a bud that is just opening and eats the developing needles. While still young, it can make spot mines in the top of a needle. During most of its life it is protected by the bud scales that do not fall off because they are secured with silk.
The adults become active near sunset and later come to light.
The adults fly from late June towards mid-August.
It inhabits spruce and pine forests, plantations, parks and gardens and similar situations where there are ornamental conifers.
