DiversityThe genus includes about 500 species in 15 subgenera.[1][2] Selected species
For a complete list, see List of Coelioxys species. DistributionCoelioxys species can be found in most European countries, in the Afrotropical realm, in the East Palearctic ecozone, in North Africa, in the Nearctic and Neotropics.[3][1]DescriptionBees within this genus can reach a length of {{convert|8|-|12|mm}}. They show a broad head with large complex eyes and broad thorax and abdomen. Their body is only moderately hairy. They are usually black with white hair stripes. Legs maybe red or black. The females of Coelioxys species have a long pointed abdomen that resembles a cone, used to pierce the leaf lining in the laying of eggs. The male's abdomen is armed with spines or teeth.[1] BiologyThese cuckoo bees are usually active from June to September, depending on the specific host species. They have no pollen-carrying adaptations, as they do not need to provision nests. Adults feed on nectar at flowers of a wide range of different nectar plants. In fact they mainly lay their eggs in the nests of bees in the genus Megachile, but also in the nests of Osmia and Anthophora, on their provisions of pollen. As this behavior is similar to that of cuckoos, such bees are sometimes referred to as "cuckoo bees". These host-parasite relationships are quite complex. The larvae of Coelioxys species kill the host larvae with their strongly developed mandibles and feed on the host’s pollen provisions. They spin a cocoon at 11–16 days. These species are usually univoltine, but for some species a second generation is possible.[1][4] GalleryReferences1. ^1 2 3 {{cite web|title=Genus Coelioxys - Cuckoo-leaf-cutter Bees|url=http://bugguide.net/node/view/7605#counts|website=BugGuide.net|accessdate=5 October 2014}} 2. ^{{cite web |url=https://www.itis.gov/servlet/SingleRpt/SingleRpt?search_topic=TSN&search_value=154378 |title=ITIS Standard Report Page: Coelioxys|accessdate=25 November 2014}} 3. ^Fauna europaea 4. ^{{cite web|title=Bees of the Week: genus Coelioxys|url=http://thebeesneeds.wordpress.com/2014/07/24/bees-of-the-week-genus-coelioxys/|website=The bees needs|accessdate=6 October 2014}}
