Erichson, 1843

Omosita is a of ( ) erected in 1843. The genus comprises five described distributed across the Holarctic and regions. Omosita species are notable for their association with stored products and carrion, with documented forensic significance due to their presence on human remains. have been recovered from decomposing human bone and successfully analyzed for human mitochondrial .

Habitat

Associated with stored products and carrion environments. O. nearctica has established breeding in South Africa after introduction from its Nearctic range.

Distribution

Holarctic distribution with . range includes Nearctic (O. nearctica) and Palearctic regions. Documented establishment in South Africa for O. nearctica.

Host Associations

human remains - found on decomposing boneforensic significance; mtDNA recovery demonstrated

Life Cycle

Larval stage has been documented on human remains and in stored product environments. Mature of O. nearctica have been formally described.

Behavior

have been recovered from late decompositional stage human remains. Associated with carrion and stored products.

Human Relevance

Storedproduct pest with biosecurity risk potential. Forensic utility: yield human mitochondrial from remains, demonstrating value in forensic entomology for badly decomposed cases.

Forensic DNA recovery

First demonstration of human mtDNA recovery from ; Omosita spp. larvae collected from human skeletal remains yielded mtDNA matching the individual.
