They studied the attractiveness of vespid
wasp to volatile materials produced from green-lipped mussel and compared with different kinds of meat.
The striking mid-season increase in vespid abundance (Fig.
5 m) of 12 trees in a temperate deciduous forest yielded 522 vespid wasps.

including dipterans, as well as hymenopterans such as vespids

Some of the largest species are of aposematic colouration and are probably Batesian mimics of aggressive vespids
Charts from a total of 122 patients seen between 1995 and 2000 in EDs in California's Sacramento and San Joaquin Valleys were reviewed retrospectively Bee stings caused 70% of the reactions, and vespids

Polistes is a large, cosmopolitan genus of eusocial wasps, and like other social vespids
, its members can create environmental problems when introduced to novel environments.
The females of a few solitary vespids may oviposit after they have stored the larval food and some are progressive provisioning during the early larval period (eg, see Cowan 1991).
dyscherus, most mud-daubing vespids obtain their mortar for nest construction by drinking water at one place and then flying to a site of dry, clayey soil where they bite at the ground, regurgitate water, and mix the resulting mud to the proper consistency (Iwata 1938, 1939).
