- Macratriinae(antlike flower beetles)
- Notoxinae(Monoceros beetles)
- Tomoderinae
is a of beetles comprising over 3,500 in approximately 100 . Members are commonly known as -like flower beetles due to their striking morphological resemblance to ants. The family is characterized by a constricted forming a distinct neck and slender appendages that enhance the ant-mimicry. are , feeding on small arthropods, pollen, fungi, and other available materials. The family has fossil representatives dating to the Early Cretaceous (Barremian) from Lebanese amber.

Identification
Distinguished from actual ants (Formicidae) by the presence of hardened forewings () characteristic of Coleoptera, versus the membranous wings or wingless condition of ants. Separated from other -mimetic beetles by the combination of constriction forming a neck, narrow pronotum, and slender appendages. The Notoxidae is now synonymized with . Resemblance to some members of Staphylinidae (rove beetles) may occur, but Anthicidae possess complete elytra covering the .

Habitat
Diverse terrestrial ; specific microhabitat preferences vary by . frequently associated with flowers and vegetation. Some species found in decaying organic matter and soil environments. Larval habitats include soil, decaying wood, and plant roots.
Distribution
Worldwide distribution with records from North America (including Vermont), Europe (Denmark, Norway, Sweden), and other regions. The is globally distributed across multiple continents.
Diet
are , consuming small arthropods, pollen, fungi, and opportunistically available organic materials. Some prey on and larvae of pest insects. Larvae exhibit varied feeding strategies: omnivory, , or . Larvae of Notoxus species have been documented boring into sweet potato tubers.
Host Associations

Life Cycle
Complete with , larval, pupal, and stages. Larvae display diverse feeding ecologies including omnivory, , and depending on . Specific developmental details vary among the approximately 100 .
Behavior
Many are attracted to , which they accumulate as a chemical defense against . are frequently observed on flowers. Some species have been documented as agents due to on pest and larvae.
Ecological Role
consumers and in terrestrial . Some contribute to of agricultural pests through on and larvae. Role in pollination via flower visitation is likely but not well documented. accumulation suggests chemical defense-based predator deterrence.
Human Relevance
Some utilized as agents for pest management. Occasional minor agricultural impact through larval feeding on crop roots (e.g., sweet potato). Generally considered beneficial or neutral in human-modified environments.
