Abstract

Species composition and distribution of the horntails (Hymenoptera, Siricoidea) of Estonia.

Abstract

Data on the species composition and Estonian distribution of horntails are revised. Eight species (Sirex juvencus, S. noctilio, Urocerus gigas, U. fantoma, Xeris spectrum, Tremex fuscicornis, Xiphydria camelus, X. prolongata) are recorded in Estonia. Notes on the location found and UTM grid distribution maps, as well as data on general distribution and host trees species found, are presented. At least two additional species (X. picta and Konowia betulae) are expected to occur in Estonia.
