IMGP0754stacks.JPG.jpg8-Apr-2005Faces of the 3 righthand stacks of nest blocks, showing packing and some mud stoppers visible from the front.Hallett, Peter
Quietus_a040810.jpg.jpg10-Aug-2004The female Trypoxylon lactitarse alighted to re-sting her spider prey before entering her nest.Hallett, Peter
IMG0013.jpg.jpg2000Fly (Amobia sp., probably A. distorta, inquiline of Symmorphus, Ancistrocerus and Trypoxylon), Mason Bee (Osmia tersula), Potter Wasps (Ancistrocerus).Hallett, Peter
IMGP0240I.mexicana.JPG.jpg29-Jul-2004Grass nests of the cricket-hunting wasp Isodontia mexicana at various stages of development.Hallett, Peter
DSCN0367.JPG.jpg15-Jun-2006Here Osmia lignaria not only seized the unused space but, etc. (Ditto).Hallett, Peter
DSCN0369olA_superseding_imA.JPG.jpg15-Jun-2006Here Osmia lignaria not only seized unused space but, etc. Again, note the cocoon remnant.Hallett, Peter
DSCN0366olA_superseding_imA.JPG.jpg15-Jun-2006Here Osmia lignaria not only seized unused space but the records, and the severed cocoons, showed that the Isodontia nests were cut back to make more space. I believe this is more likely if there is no Isodontia nest stopper of protruding long straws but only a fibrous cross wall.Hallett, Peter
IMGP0940ocA_or_mpA.JPG.jpg6-Jul-2005If these nests develop overwintering dark adults (orange coated males in anterior cells) the diagnosis is Osmia coerulescens, if not it is Megachile pugnata (there are suggestions of bilaminate cross walls here; the female should have spinous cheeks).Hallett, Peter
IMGP0342.JPG.jpg17-Aug-2004Immatures of the resin-using bee Megachile campanulae.Hallett, Peter
IMGP0341Trypoxylon_collinumq.JPG.jpg17-Aug-2004immatures of the wasp Trypoxylon collinum with cocoons of various ages, and remains of spider provisions.Hallett, Peter
DSCN0621LAU312C_b3-5_olA-db_invaded_by_imA-fk.JPG.jpg16-Sep-2006In the upper cavity (#5) Osmia lignaria was killed by emergence of generation 2005 Isodontia. In cavity 3 it is perhaps moot whether Osmia was killed by the emergence of the inner Isodontia nest of generation 2005 or by invasion from outside by '2006' Isodontia.Hallett, Peter
DSCN0370olA_superseding_olA.JPG.jpg15-Jun-2006In this case new generation Osmia lignaria have built in front of the old, blocking emergence.Hallett, Peter
Img_stand_save00024.jpg.jpg4-Jun-2002In year 2002 only, the 3 boxes of the 2001-6 period were stacked vertically on the 2 stands at all 3 locations (Saugeen, Monastery, Jokers).Hallett, Peter
iso_thinking040902.JPG.jpg2-Sep-2004Isodontia mexicana nests at various stages.Hallett, Peter
DSCN0372.JPG.jpg18-Jun-2006It is too early to say if the sickly late larva etc. (Ditto).Hallett, Peter
DSCN0371olA_with_pathogen.JPG.jpg18-Jun-2006It is too early to say if the sickly late larva will develop into a black liquid ('foul brood-like pathogen') or a black fur ('black fungus'). The former is more usual.Hallett, Peter
T.latitarselarva040729.jpg.jpg29-Jul-2004Larva of Spider-hunting Wasp (Trypoxylon lactitarse)Hallett, Peter
DSCN0340smallAnthrax.JPG.jpg16-May-2006Larva on its Symmorphus cristatus host.Hallett, Peter
DSCN1537_ml115_Chaetodactylus_Mite.JPG.jpg29-Mar-2009LAU115, 4.8 mm cavities. Chaetodactylus mites 'boiling over'. Mainly Osmia lignaria nests. The very small besieging O. coerulescens and Megachile (probably rotundata) nests in cavities 3 and 6 were killed by O. lignaria's mites and exit respectively.Hallett, Peter
DSCN1538_ml116_olA_v_mAB_lls_wars.JPG.jpg29-Mar-2009LAU116, 4.8 mm cavities. Osmia lignaria in various conflicts with mutual losses: cavities 1 and 2 (left) with Megachile (probably rotundata), in cavity 6 with M. campanulae. The besiegers all died, as did O. lignaria in cavities 2 and 6.Hallett, Peter
