Sphecidae (Trypoxyloninae) (Sphecoidea) -- <Images> & <Juveniles> Please refer also to the following links for details on this
group: Trypoxyloninae In the subfamily Trypoxyloninae,
nests are often constructed of a large number of mud cells, arranged often in
tubular form on a solid surface. Each
aggregation may comprise the cells of a number of successive
generations. Other species use
crevices or holes in walls, stems, etc., or they may burrow in soil. Almost always they provision their cells
with spiders (Clausen 1940/1962). Peckhams (1895, 1898) studied Trypoxylon rubrocinctum Peck. and T.
albopilosum Fox, where females
utilize existing burrows in woodwork or masonry that have been
abandoned. T. rubrocinctum
provisions its cells with 7-12 spiders, while T. albopilosum, being
larger, requires 25-30. Prey may
represent many genera and even families, although the majority usually are in
the Epeiridae. An egg is laid on the
side of the abdomen's dorsum of the last spider placed in the cell (Clausen
1940/1962). =
