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
DSCN1539_ml116_olA_v_mcA_war_notclear.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
DSCN1543_ml145_olA_v_Hylaeus.JPG.jpg6-Apr-2009LAU145, 4.8 mm cavities. Cavity 1 shows Osmia lignaria mud nest followed by the 'bee cellophane' bubble nest of Hylaeus.Hallett, Peter
DSCN1540_ml145_olA_v_Hylaeus.JPG.jpg6-Apr-2009LAU145, 4.8 mm cavities. Cavity 1 shows Osmia lignaria mud nest followed by the 'bee cellophane' bubble nest of Hylaeus.Hallett, Peter
DSCN1545_ml1452_Hylaeus_v_ocA_war.JPG.jpg6-Apr-2009LAU145, 4.8 mm cavities. Cavity 2: Hylaeus bees blocked by Osmia coerulescens with mutual casualties.Hallett, Peter
DSCN1544_ml1452_blocked_Hylaeus.JPG.jpg6-Apr-2009LAU145, 4.8 mm cavities. Cavity 2: Hylaeus bees blocked by Osmia coerulescens with mutual casualties.Hallett, Peter
DSCN1542_ml145_mAB_lls_almostlike_llb.JPG.jpg6-Apr-2009LAU145, 4.8 mm cavities. It is often difficult to distinguish between putative Megachile relativa (cross-walls visible) and putative M. rotundata (cross-walls hidden, 'dixie cup' or apparent spiral structure).Hallett, Peter
DSCN1541_ml145_mAB_lls_almostlike_llb.JPG.jpg6-Apr-2009LAU145, 4.8 mm cavities. It is often difficult to distinguish between putative Megachile relativa (cross-walls visible) and putative M. rotundata (cross-walls hidden, 'dixie cup' or apparent spiral structure).Hallett, Peter
