DSCN0365.JPG.jpg15-Jun-2006Early cocoon spinning by Osmia lignaria. Some of the cocoons are still translucent. Most of the pollen is gone.Hallett, Peter
DSCN0345ectopicOsmia_lignaria.JPG.jpg25-May-2006Ectopic cells of Osmia lignaria built in the gap between 2 stacks of nest blocks. In 2006 there was severe crowding at the Monastery with only 14 in 1249 cavities empty. In addition 794 of 1080 O. lignaria nests were harvested in an effort to preserve biodiversity.Hallett, Peter
DSCN0346.JPG.jpg25-May-2006Ectopic cells of Osmia lignaria, etc. (Ditto).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
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
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
DSCN0474aLAU154A_aAB_mcA_war.JPG.jpg15-Aug-2006LAU stand, block 154, 4.8 mm cavities. In cavity 6 up a small Osmia lignaria nest, new in June, had been replaced in August by a Potter (probably S. cristatus). The Potter failed but the outer resin-using Megachile campanulae apparently emerged next Spring.Hallett, Peter
DSCN0475LAU157B_mAA-tcA_q-mcAsequence.JPG.jpg15-Aug-2006LAU stand, block 157, 6.4 mm cavities. All 4 generation 2006 nests in cavity 4 up died. In order: the Osmia lignaria nest of Spring failed to develop and was scraped out by me; the leaf-rolling Megachile and Trypoxylon collinum summer nests, still alive here, developed dead adults, and the outer M. campanulae nest, alive here, was wrecked during the attempted exits from the earlier nests..Hallett, Peter
DSCN0476detail_posterior.JPG.jpg15-Aug-2006LAU stand, block 157, 6.4 mm cavities. Anterior detail of cavity 4: the Trypoxylon versus M. campanulae conflict.Hallett, Peter
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
