Observations on life cycle and feeding ecology of two recently introduced predatory beetle species at South Georgia, sub-Antarctic

On South Georgia, two recently introduced species of predatory beetle,Oopterus soledadinus andTrechisibus antarcticus (Coleoptera, Carabidae), were studied in the period November 1991–April 1992. The study area comprised the coastal area around Stromness Bay, in particular the surroundings of the ab...
