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
DSCN1546_ml146_mAB_lls_nocrosswall.JPG.jpg6-Apr-2009LAU146, 4.8 mm cavities. Absence of a visible crosswall consistent with possibility of Megachile rotundata. Note pin holes suggestive of the pest Melittobia.Hallett, Peter
DSCN1547_ml147_mAB_lls_nocrosswall.JPG.jpg6-Apr-2009LAU147, 4.8 mm cavities. Leaf-rollings of putative Megachile rotundata above solid resin nest of Megachile campanulae.Hallett, Peter
DSCN1548ml148_tcA_msi_coin.JPG.jpg6-Apr-2009LAU148, 4.8 mm cavities. Cavity 2: Trypoxylon collinum. Smaller than T. lactitarse, the front of the cocoon is flat with a small central pimple.Hallett, Peter
DSCN1549_ml156_mrB_llb_crosswallsjustvisible.JPG.jpg8-Apr-2009LAU156, 4.8 mm cavities. Megachile leaf-roller with pinholes made by Melittobia.Hallett, Peter
DSCN1550_ml157q_sleepy_ocA_rd.JPG.jpg9-Apr-2009LAU157, 4.8 mm cavities. Willowdale. Spring time but still sleepy: female on left, male on right of Osmia coerulescens.Hallett, Peter
DSCN1551_ml15X_Potter_scB_Chrysis.JPG.jpg9-Apr-2009LAU15X, 4.8 mm cavities. Cocoons of the Potter Wasp Symmorphus cristatus and the common parasitoid, the Cuckoo Wasp Chrysis coerulans.Hallett, Peter
DSCN1553_olA_nesting.JPG.jpg10-May-2009LAU2XX, 6.4 mm cavities. Spring 2009. Nests of all species show a tendency to cluster, and in many cases clusters of females are seen.Hallett, Peter
DSCN1552_olA_nesting.JPG.jpg10-May-2009LAU2XX, 6.4 mm cavities. Spring 2009. Nests of all species show a tendency to cluster, and in many cases clusters of females are seen.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
