IMGP0328ocA_aaA.JPG.jpg12-Aug-20041st and 3rd cavities the bee Osmia coerulescens, others the wasp Ancistrocerus antilope.Hallett, Peter
IMGP0293O.coerulans_orM.campanulae.JPG.jpg9-Aug-20043.2 mm cavities. A difficult diagnosis because of the narrow cavities. Probably not Heriades carinata, as resin opaque and abundant, more likely Megachile campanulae, and not Osmia coerulescens as apparently pure resin with no obvious leaf pulp.Hallett, Peter
S_candensis040725a.JPG.jpg25-Jul-20043.2 mm cavities, all with the provisions and pale larvae of Symmorphus canadensis.Hallett, Peter
Sibling_emerge040815.jpg.jpg15-Aug-20043.2 mm cavities. 'Artificial release' of Symmorphus canadensis.Hallett, Peter
IMGP0333.JPG.jpg15-Aug-20043.2 mm cavities. Cavity 6 (3 up) shows the chunky black chrysomelid provisions and vivid Yellow prepupa of S. cristatus. Cavities 7 and 8 are S. canadensis, 7 because of the whitish host larvae and 8 because of orange weevil provisions.Hallett, Peter
DSCN0392_3smallpotters.JPG.jpg25-Jun-20063.2 mm cavities. Female Symmorphus resting at 08:00.Hallett, Peter
DSCN0390tfA_nest.JPG.jpg24-Jun-20063.2 mm cavities. From left to right, the bee Hylaeus, the Potter Symmorphus cristatus, and the spider-using Trypoxylon frigidum.Hallett, Peter
DSCN0387.JPG.jpg24-Jun-20063.2 mm cavities. If one searches enough some overwintering nests show changes in prepupal colour and sex. Here, an abrupt change in provisioning is also consistent with the possibility of a change in Symmorphus species, from S.canadensis at left to S. cristatus at right.Hallett, Peter
IMGP0879mixedSymmprphus_Chrysis.JPG.jpg15-May-20053.2 mm cavities. Mixed Symmorphus and Chrysis cocoons.Hallett, Peter
DSCN0383_3.2mm_block.JPG.jpg24-Jun-20063.2 mm cavities. Mother Potter Wasp, Symmorphus canadensis.Hallett, Peter
DSCN0384scA_on_nest.JPG.jpg24-Jun-20063.2 mm cavities. Mother Potter Wasp, Symmorphus canadensis, provisioning.Hallett, Peter
IMGP0211Symmorphus_3.2mmBW.JPG.jpg25-Jul-20043.2 mm cavities. Possibly entirely the small Potter Wasp Symmorphus canadensis.Hallett, Peter
IMGP0213detail.JPG.jpg25-Jul-20043.2 mm cavities.Possibly entirely the small Potter Wasp Symmorphus canadensis. Detail 1.Hallett, Peter
IMGP0215S.canadensis_pupa_emerged.JPG.jpg25-Jul-20043.2 mm cavities. Possibly entirely the small Potter Wasp Symmorphus canadensis. Detail 2. Note the almost mature pupa in cavity 7 (2 down) and the adult male moving towards the end of the nest block. These are not uncommon sights for Symmorphus canadensis.Hallett, Peter
DSCN0386scAq_3.2mmBW.JPG.jpg24-Jun-20063.2 mm cavities. Potter Wasp, Symmorphus probably canadensis.Hallett, Peter
IMGP0937scB_mb.JPG.jpg2-Jul-20053.2 mm cavities, some provisioned with chrysomelid beetle larvae for Symmorphus cristatus.Hallett, Peter
IMGP0329.JPG.jpg15-Aug-20043.2 mm cavities. Symmorphus canadensis.Hallett, Peter
IMGP0292S.canadensis_bee_3.2mmBW.JPG.jpg8-Aug-20043.2 mm cavities. Symmorphus canadensis and the bee Heriades carinata (at right) that builds resin cross walls in the narrowest cavities.Hallett, Peter
IMGP0349scA_mums.JPG.jpg28-Aug-20043.2 mm cavities. Symmorphus canadensis mothers. Cavity 5 (5 from left) shows the long thin and very small leaf miners and sawflies often used by this small Potter Wasp.Hallett, Peter
IMGP0332.JPG.jpg15-Aug-20043.2 mm cavities. Symmorphus canadensis mothers. Cavity 6 (2 up) shows the very small weevils immatures often used by this small Potter Wasp..Hallett, Peter
