More tree wasps (Lat: Dolichovespula norwegica) have nested in south Iceland this summer than in 2008 due unusually warm and dry weather conditions. The nests are growing not only in number but also in size.
Entomologist Erling Ólafsson at the Icelandic Institute of Natural History (NÍ) said that wasp nests had grown incredibly fast in July and that sometimes more than one wasp nest had been found in the same garden, as reported on NÍ’s website.
It is uncertain whether the conditions have also been fortunate for hole wasps (Lat. Paravespula vulgaris)—their nests are rarely visible until in late summer.
The house wasp (Lat. Paravespula germanica) has not been noticed this summer—the species has been struggling for the past years.
