Insektsfynd vid Biologiska institutionens bioblitz i Lund i juni 2018

A 24-hour bioblitz was performed by employees in the immediate surroundings of the Biological Institute in the city of Lund, South Sweden, on the 15th of June 2018. It produced 928 taxa, 411 of which were insects. Six species of Hymenoptera Parasitica were new to Sweden: Tumidiclava bimaculata (Blood), Lathromeris germanica (Girault), Aprostocetus crassiceps Graham, Quadrastichus anysis (Walker), Metaphycus chermis (Boyer de Fonscolombe) and Trissolcus semistriatus (Nees von Esenbeck). A further handfull insect species were red-listed. Although more species remain to be identified, the brief investigation showed unexpected biodiversity and complex ecological interrelationships in urban nature. This was partly due to a surprisingly high diversity of insect herbivores, their parasitoids and predators as a function of strong plant variation in the surroundings of the institute.
