IMGP0879mixedSymmprphus_Chrysis.JPG.jpg15-May-20053.2 mm cavities. Mixed Symmorphus and Chrysis cocoons.Hallett, Peter
IMGP0937scB_mb.JPG.jpg2-Jul-20053.2 mm cavities, some provisioned with chrysomelid beetle larvae for Symmorphus cristatus.Hallett, Peter
IMGP0951.JPG.jpg17-Jul-20053.2 mm cavities. Two weeks later. A mix of immature stages, earliest at the front.Hallett, Peter
IMGP0950scA_emerge.JPG.jpg17-Jul-20053.2 mm cavities. Two weeks later some of the generation 2005 Symmorphus canadensis are already weakly pigmented pupae (cavity 1 at top).Hallett, Peter
IMGP0935.JPG.jpg1-Jul-20054.8 mm cavities in early summer. At the same date the provisions are gone and slightly shrunken bright yellow prepupae are seen in neighbouring cavities.Hallett, Peter
IMGP0934S.cristatus_prey.JPG.jpg1-Jul-20054.8 mm cavities in early summer. The 'bloated' larvae and beetle larvae provisions are well shown.Hallett, Peter
IMGP0743potter_prepupal_colours.JPG.jpg21-Mar-2005Cavity width, provisioning and overwintering prepupal colour allow good but not perfect sorting of Symmorphus canadensis and S. cristatus.Hallett, Peter
IMGP0748.JPG.jpg21-Mar-2005Overwintering prepupal colours of the two sister species of Symmorphus Potter Wasps.Hallett, Peter
IMGP0745potter_prepupal_colours.JPG.jpg21-Mar-2005Similar but different lighting.Hallett, Peter
IMGP0746.JPG.jpg21-Mar-2005Similar but different lighting. The sorting here was very rapid! Massed well-lit material (e.g., by bright daylight) is much better differentiated than singletons within the nest block. Long and repeated inspection also helps.Hallett, Peter
IMGP0936scB_mb.JPG.jpg2-Jul-2005Typical appearance of Symmorphus cristatus but in the smaller less common 3.2mm cavity width.Hallett, Peter
IMGP0882a_WES_hivestand.jpg.jpg5-Jun-2005WES stand in Spring.Hallett, Peter
