 Satellite nests are common among P. exclamans . A queen will fly somewhere between 0 @.@ 15 and 11m away from the original nest to settle in a new location . About 16 – 39 % of nests create satellites from May to July . Similar to the wasp species , <unk> <unk> , constructing multitude of nests in clusters in order to create protection through dilution effect , the satellites are used as an insurance against attacks by predators and parasitoids . Of 12 nests that were knocked down by birds that had satellites , 66 @.@ 7 % of the colony survived by moving to the satellite , compared to the reproductive success of nests with no satellite that were attacked ( 5 @.@ 7 % ) . When Chalcoela iphitalis invades , the prevalence of satellites didn ’ t increase the survivability , however it did have an effect when Elasmus polistis were introduced . It gave the P. exclamans a place to escape to .
