Colon (bille)

Colon er en slekt av jordbiller med et skjult, underjordisk levesett. Mange arter finnes i gangene til gnagere og andre små pattedyr.

Utseende 
Små, avlange, fint hårete, vanligvis matt brunlige biller. Hodet er oftest kraftig innskåret bak fasettøynene, med en smal hals, men dette kan være vanskelig å se da billene gjerne trekker hodet inn under brystskjoldet. Antennene er forholdsvis korte og gradvis utvidet utover, uten en klart definert kølle eller påfallende små ledd. Beina er kraftige og ofte tilpasset graving.

Levevis 
Artene lever vanligvis under bakkenivå og finnes særlig i ganger og bol av gnagere og andre småpattedyr, der de trolig lever av avfall.
De er en gruppe man sjelden ser, men som neppe er sjeldne.
