Chaetophiloscia sicula
Chaetophiloscia sicula is a small (~6 mm) terrestrial isopod native to the northern Mediterranean region. First recorded in North America in 2000 in Baltimore, Maryland, it has since spread to at least nine U.S. states and Washington D.C., primarily through human-aided dispersal associated with urban environments. The species exhibits strong habitat preferences for anthropogenic settings such as gardens and urban parks, as well as coastal areas including upper sandy beaches and jetties. Its rapid expansion across North America and Europe is facilitated by affinity to moist, disturbed habitats and potential transport via the pet trade and potted plants.
Ochthebius
minute moss beetles
Ochthebius is a large genus of minute moss beetles in the family Hydraenidae, comprising at least 460 described species. These tiny beetles are predominantly associated with aquatic and semi-aquatic habitats, particularly supratidal rockpools, coastal marshes, and freshwater spray zones. Many species exhibit narrow habitat preferences and restricted distributions, with numerous endemic taxa. The genus shows significant diversity in the Mediterranean region, Africa, and other parts of the world, and includes several cryptic species complexes.
