Temperature, floral density, and Osmia pollen usage data from seven study sites around the Rocky Mountain Biological Laboratory, Colorado: 2013-2023
Data were collected as part of a study of population dynamics of solitary, cavity-nesting Hymenoptera. Nesting structures ("trap-nests") were established at five study sites along an elevational gradient around the Rocky Mountain Biological Laboratory in 2013. Two additional study sites were added in 2014, and one of the original study sites was dropped at the end of 2015. At each site, a HOBO data-logger placed under a centrally located trap-nest records air temperatures hourly. Floral densities are recorded at each site, typically 1-2 times per week, throughout the growing season, for specific plant taxa known to be used as pollen sources by cavity-nesting bees. In addition, pollen samples are taken from the nests of cavity-nesting bees and the constituent plant taxa identified by microscopic comparison with a reference pollen collection from the study area.

Fig. 10 in First record of a gynandromorph of Osmia submicans MORAWITZ, 1870 (Hymenoptera, Megachilidae) - characterisation by morphological and morphometric parameters and critical note on gynander classification
Fig. 10: PCA of 34 morphological parameters in females, males and the left and right side of the gynander (variance-covariance matrix). Pink dot = females; bluish square = males, cross = gynander left, circle = gynander right. Eigenvalue axis 1 = 0.6535, % variance = 84.67; eigenvalue axis 2 = 0.0580, % variance = 7.516.
Fig. 6 in First record of a gynandromorph of Osmia submicans MORAWITZ, 1870 (Hymenoptera, Megachilidae) - characterisation by morphological and morphometric parameters and critical note on gynander classification
Fig. 6: On the left side, the sternites with male characteristics are visible. They show the greenish ore-coloured integument which is also typical for males. The large S2 is characteristic for males. On the right side the smaller female sternites are formed, bearing the black metasomal scopa; photo: L. Haitzinger.
Fig. 5 in First record of a gynandromorph of Osmia submicans MORAWITZ, 1870 (Hymenoptera, Megachilidae) - characterisation by morphological and morphometric parameters and critical note on gynander classification
Fig. 5: The metasoma has a greenish-bronze to ore-coloured integument on the left dorsal side and a golden yellow pubescence on the tergite ends of T1-T3 and T6 (male characteristics). On the right side, it has a black (dark bluish) integument and a white pubescence (female characteristics). In T4, the left side has purely male characteristics, while the right side is female on one side and male on the other. T5 has male characteristics throughout; photo: L. Haitzinger.

Fig. 3 in First record of a gynandromorph of Osmia submicans MORAWITZ, 1870 (Hymenoptera, Megachilidae) - characterisation by morphological and morphometric parameters and critical note on gynander classification
Fig. 3: Areas of the gynander with female (pink) and male (blue-violet) morphological features, schematised (left = dorsal side; right = ventral side). The results for femura, tibia, metatarsi and tarsi 5 were assigned on the basis of the morphometric results. In ventral view, the left side corresponds to the right half of the body, the right side to the left half of the body. No differences could be detected in areas marked in grey.
