to the following links for further details:č Nomadinae (previously under
Anthophoridae).-- = Link 2 These are the cuckoo bees, which are
parasites in the nests of other bees.
They resemble wasps in that their bodies are relatively free of
hairs. Clausen (1940) considered
Nomadidae under the Apoidea. The
members of the family are mostly inquilines in the nests of various solitary
bees. Graenicher (1905b) presented an
account of these insects as an inquiline in the nests of robber flies. The egg of Triepoelus
is thought to be laid in the food material.
The abdominal segments bear a flat triangular projection at each
lateral margin. The very large
falcate mandibles are thought to be for use against larvae of their own kind
rather than against that of the host bee.
Perkins (1919) reviewed the host preferences of a large number of
species and found each of them to be closely associated with a particular
solitary bee species. This is a diverse group
of cleptoparasitic "cuckoo bees" with 32 genera. They are cosmopolitan, and attack many
different kinds of bees , which they use as hosts. As parasitoids, they lack a
pollen-carrying scopa, and are usually wasp-like in appearance. Females enter the host nests when the host
is not present. They deposit their
eggs in the wall of the host cell, and the larval parasitoid emerges after
the cell has been closed by the host female.
The host larva is then killed. The first-instar larvae are adapted for
this with their long mandibles that are deployed for killing. The mandibles lost after the first instar.
Then the larva feeds on the nectar and pollen stores. Some species have been
observed to remain quiescent while holding onto the plant with their
mandibles. = = = = =
