DSCN0477detail_anterior.JPG.jpg15-Aug-2006LAU stand, block 157, 6.4 mm cavities. Posterior detail of cavity 4: the Megachile leaf-roller versus Trypoxylon conflict.Hallett, Peter
DSCN0471aAB_tlA_war.JPG.jpg15-Aug-2006LAU stand, block 1XX. Below up: bee Osmia lignaria, and wasps Ancistocerus antilope and Trypoxylon lactitarse. In the upper cavity one can just make out the shining dark brown Trypoxylon cocoons.Hallett, Peter
DSCN0625LAU316C_b1-3_imA-fk_and_olA-db_wars.JPG.jpg21-Sep-2006LAU stand, block 316, 8.0 mm cavities. The generation 2006 nests are all the mud-using bee Osmia lignaria which shows some losses to mites. The generation 2005 Isodontia nests all died from cutback and blocking.Hallett, Peter
DSCN0626LAU317B_b6_Anthrax_in_ocA_nest.JPG.jpg21-Sep-2006LAU stand, block 317, 6.4 mm cavities. In the Fall it is easy to pull Osmia coerulescens bees and sometimes their parasitoids (Anthrax here) from their nests (and successfully pop them back in again if there are no 'mitey' Osmia lignaria in adjacent cavities).Hallett, Peter
DSCN0489-b2_detail_midanterior.JPG.jpg16-Aug-2006LAU stand, block 325, 8.0 mm cavities. Detail of cavity 2.Hallett, Peter
DSCN0488LAU325C-b2_imA-olA_war.JPG.jpg16-Aug-2006LAU stand, block 325, 8.0 mm cavities. In cavity 2 up the doomed Isodontia adults of generation 2005 only managed to penetrate two mud cells of the generation 2006 Osmia lignaria during their attempted exit.Hallett, Peter
DSCN0493_detail.JPG.jpg16-Aug-2006LAU stand, block 331, 6.4 mm cavities. A very rare type of Potter for this Data Set, versus Osmia lignaria. Although Potter versus Osmia conflicts are common it is extremely rare indeed, despite many observations and hatches, to have evidence of a Potter that is neither Ancistrocerus or Symmorphus in this Data Set. A broad yellow abdominal stripe can just be glimpsed in the generation 2005 Potter nest in cavity 1 up.Hallett, Peter
DSCN0494LAU3341B-b1_Hylaeus_in_old_potter_nest-ocA_war.JPG.jpg16-Aug-2006LAU stand, block 334, 6.4 mm cavities. This detail of cavity 1 shows dead, wasp-like, Hylaeus bees of generation 2005 or 6 within a failed 2005 Ancistrocerus nest. The cause of death is blocking of emergence by a small generation 2006 Osmia lignaria nest. The O. lignaria nest was itself cutback completely by O. coerulescens (out of picture). This last was parasitized by a bombyliid.Hallett, Peter
DSCN0599LAU335A_b1_ocA_nest_bombyliid_unwintered_exit.JPG.jpg15-Sep-2006LAU stand, block 335, 4.8 mm cavities. Detail of cavity 1 up. The O. coerulescens nest harboured a Bee Fly which emerged without wintering (its characteristic pupal skin remains at the cavity entrance).Hallett, Peter
DSCN0598LAU335A.JPG.jpg15-Sep-2006LAU stand, block 335, 4.8 mm cavities. General view showing Osmia lignaria and O. coerulescens nests in good condition,. Cavities 1 and 2 up show remnants of O. lignaria and Potter, probably Symmorphus cristatus, nests that have been damaged and blocked by O.coerulescens.Hallett, Peter
DSCN0600LAU336B_b4_unwintered_bombyliid_exit_fails.JPG.jpg15-Sep-2006LAU stand, block 336, 6.4 mm cavities. Detail of cavity 4. This generation 2006 Potter nest, probably Symmorphus cristatus, harboured a Chrysis and 4 bombyliids. These two bombyliids failed to emerge unwintered, killing two more of the host in their attempt. Note the black adult flies with their large compound eyes within the clear pupal skins.Hallett, Peter
DSCN0601LAU337C_b4_imA-fk_olA-db_warq.JPG.jpg15-Sep-2006LAU stand, block 337, 8.0 mm cavities. Detail of cavities 1-4. The generation 2005 Isodontia in cavities 1 and 3 emerged before the late summer biennial bee Osmia texana built its nest. That in cavity 4 was trapped by the Spring nesting bee Osmia lignaria.Hallett, Peter
DSCN0602LAU338B_b1-3_ocA-rd_olA-db_war.JPG.jpg15-Sep-2006LAU stand, block 338, 6.4 mm cavities. Cavity 2 contained a generation 2005 nest of Osmia coerulescens that was blocked by generation 2006 O. lignaria. The O. coerulescens destroyed the O. lignaria in their exit attempt but had not yet breached the nest stopper. Two O. coerulescens were dead and two flew during the inspection.Hallett, Peter
DSCN0603LAU341C_b2n5_imA-fk_olA-db_wars.JPG.jpg15-Sep-2006LAU stand, block 341, 8.0 mm cavities. Exits of generation 2005 Isodontia blocked by '2006' Osmia lignaria nests.Hallett, Peter
DSCN0604LAU343C_b1_otB-klr_1st_overwinter_stage.JPG.jpg15-Sep-2006LAU stand, block 343, 8.0 mm cavities. Cocoons of the biennial bee Osmia texana showing the first overwintering stage.Hallett, Peter
DSCN0605LAU344Bposed_b4-6.JPG.jpg15-Sep-2006LAU stand, block 344, 6.4 mm cavities. Detail.Hallett, Peter
DSCN0606LAU344Bposed_b6_BO_in_ocA_b4_CK_in_olA.JPG.jpg15-Sep-2006LAU stand, block 344, 6.4 mm cavities. Posed photo with dead Anthrax bombyliids from the Osmia coerulescens nest of cavity 6 (left) and O. lignaria with chalk-brood like fungus from cavity 4. The bombyliids killed a host immature in their attempted unwintered exit.Hallett, Peter
DSCN0607LAU346D_b1_amA-ff_b2_old_imA_fail-new_olA.JPG.jpg15-Sep-2006LAU stand, block 346, 9.6 mm cavities. From below: cavity 1 shows an emerged Anthidium manicatum nest of generation 2005; cavity 2 shows a failed '2005' Isodontia nest and '2006' Osmia lignaria; cavity 3 is comparable, but with blocked '2005' Isodontia adults and '2006' O. lignaria cocoons killed in the attempted exit.Hallett, Peter
DSCN0608LAU347C_b3_imA_half_cocoon-olA.JPG.jpg15-Sep-2006LAU stand, block 347, 8.0 mm cavities. Change in nest construction from generation 2005 Isodontia grass nest to '2006' Osmia lignaria mud nest. The single Isodontia cocoon in each nest has been killed.Hallett, Peter
DSCN0609LAU347C_b3_imA_half_cocoon-olA.JPG.jpg15-Sep-2006LAU stand, block 347, 8.0 mm cavities. The same, but posed to make the cocoon cutting more obvious.Hallett, Peter
