A rare but successful reproductive tactic in a social wasp (Hymenoptera:Vespidae): Use of heterospecific nests RChHN
DE SOUZA,ANDRÉ R.; SILVA,NEWTON J. J.; PREZOTO,FÁBIO.
Successful heterospecific use of abandoned nests has been reported in birds. Although the same behavior has been observed in wasps, the success of such tactic has not been demonstrated. We described two cases in which the social wasp Polistes versicolor successfully reared its brood in empty nests of the social wasps Mischocyttarus drewseni and Mischocyttarus cassununga (Hymenoptera: Vespidae). We showed that this is a rare but a viable reproductive tactic for both solitary and associative foundress. Unlike birds, which use heterspecific nests very similar to their own, wasps are able to use heterspecific nests that do differ from their own.

Colony cycle, foundation strategy and nesting biology of a Neotropical paper wasp RChHN
SINZATO,DANIELLE M. S; ANDRADE,FLÁVIO R; DE SOUZA,ANDRÉ R; DEL-CLARO,KLEBER; PREZOTO,FÁBIO.
Polistes ferreri Saussure, 1853 is a Neotropical paper wasp often found in anthropic environments. However, there is little information available on biological, ecological and behavioral interactions of this species under these environmental conditions. This study investigated the colony cycle, foundation strategy and nesting biology of this species. From March of 2000 to February of 2004, several colonies were studied in the municipal district of Juiz de Fora, in southeastern Brazil. The colony cycle events of P. ferreri are concentrated in specific periods of the year. The colonies are established principally by association of females, the latter is the foundation strategy that confers the greatest success. Nidification on manmade substrates seems common...
