The family that includes northern caddisflies is Limnephilidae. This family is a group of caddisflies characterized by their adaptations to cold, freshwater environments, which is typical of northern regions. Limnephilidae is particularly known for its diverse species that can be found in various freshwater habitats, such as rivers, lakes, and ponds, where they play essential roles in the aquatic ecosystem as both herbivores and prey for other organisms.

The other families listed do include caddisflies but are not specifically known for northern caddisflies. Hydroptilidae, for example, consists of small caddisflies that are often found in diverse freshwater habitats and have a global distribution but do not specifically represent the northern adaptations. Trichoptera is the order that encompasses all caddisflies, including Limnephilidae, rather than a specific family, while Molannidae is another family within Trichoptera, but it typically represents different ecological niches and not specifically the northern caddisflies. Thus, Limnephilidae directly identifies the family associated with northern caddisflies accurately.
