|Range Description:||Colletes hederae has been recorded from Cyprus and many parts of southern and western Europe where it is currently rapidly extending its range northwards (Ortiz-Sánchez et al. 2002; Bischoff et al. 2005; Kuhlmann et al. 2007, 2012; Roberts et al. 2011). The extent of occurrence (EOO) in Europe is 3,271,208 km² and in the EU 27 is 3,180,515 km². The area of occupancy (AOO) in Europe is 1,200 km² and in the EU 27 is 1,120 km².|

|Population:||At least in western and central Europe populations are often very large and the species is rapidly extending its range northwards and westwards (Ortiz-Sánchez et al. 2002; Bischoff et al. 2005, Kuhlmann et al. 2007, 2012; Roberts et al. 2011).|
|Habitat and Ecology:||Colletes hederae occurs in a wide range of open habitats including anthropogenic habitats like gardens or sand pits. The species is a flower visitor that preferably collects pollen on Hedera (Araliaceae) (it is polylectic, taking pollen from a wide variety of plants, but with strong preference for Hedera) (Müller and Kuhlmann 2008, Westrich 2008).|
|Use and Trade:||This species is not utilized.|
|Major Threat(s):||This species occupies anthropogenic habitats and is expanding its range, thus, is tolerant of habitat degradation.|
This species is included in the National Red List or Red Data Book of Slovenia (Endangered; Anonymous 2002).
It is recommended to conserve suitable habitats (e.g., open vegetation types with bare soil), nesting sites and the host plants of this species.
Further research is required to establish the current status of the species throughout its range and to identify the existing threats.The species occurs in protected areas.
