Concentrated vulnerabilities in bees: Diet specialists have smaller geographic ranges
Insect Conservation and Diversity, Volume 19, Issue 5, Page 1114-1123, September 2026.Niche breadth theory predicts a positive association between range size and diet breadth, which could concentrate risk among specialists, but this is not well established for bees. Using global occurrence data (range size) and natural history collection‐derived pollen data (diet breadth), we compared these traits in 633 species from six families and ...

Flagellar Sensilla of Sphecodes Bees (Hymenoptera, Halictidae)
Zoologica Scripta, 1982 The antenna of Sphecodes bees were investigated as regards the type and distribution of the sensilla. Eleven species originating from Sweden were used. Totally 325 specimens were studied. The distribution of sensilla placodea and sensilla trichodea on the antennal segments were studied in the light stereomicroscope.
