Aspidapiini
Genus Guides
2Aspidapiini is a small tribe of carpet beetles within the Dermestidae. These beetles are characterized by their association with dry organic materials and are closely related to the more diverse and economically important tribes Attagenini and Megatomini. The tribe contains relatively few described and is less well-studied than other dermestid groups.

Identification
Aspidapiini can be distinguished from related dermestid tribes by features of the antennal club and male genitalia. Unlike Attagenini, they lack the pronounced lateral compression of the body seen in many attagenines. The tribe is generally less setose than Megatomini, with reduced scaling on the .
Habitat
in this tribe are found in dry, sheltered environments where they feed on accumulated organic debris. They occur in nests of birds and mammals, in stored products, and in natural accumulations of hair, feathers, and dead insects.
Distribution
The tribe has a scattered distribution with records from the Palearctic, Nearctic, and Afrotropical regions. Specific range data for individual and remain incomplete in published literature.
Diet
Larvae feed on dry animal matter including keratinous materials such as hair, feathers, and dead insects. do not feed significantly.
Host Associations
- bird nests - larvae develop in accumulated nest debris
- mammal nests - larvae develop in accumulated nest debris
- stored products - occasional occurrence in dry organic materials
Life Cycle
Development follows the complete typical of Coleoptera: , larva, pupa, and . Larvae are the primary feeding stage and can survive extended periods without food. occurs in the last larval skin or in nearby shelter.
Behavior
Larvae are cryptic and avoid light, remaining within substrate. are short-lived and primarily dispersive, seeking mates and oviposition sites.
Ecological Role
Larvae function as scavengers, breaking down accumulated keratinous debris in vertebrate nests and similar . This contributes to nutrient cycling in otherwise nutrient-limited dry environments.
Human Relevance
Minor pests of stored products and occasionally of museum specimens. Economic impact is limited compared to the related tribe Megatomini.

Taxonomic History
Aspidapiini was established to accommodate with intermediate characteristics between Attagenini and Megatomini. The tribal boundaries have been revised multiple times, and some authors have questioned its validity as a distinct lineage.
Research Gaps
Basic , stages, and -level remain poorly documented for most in this tribe. Identification keys are limited and often require examination of male genitalia.
