Maps of the provincial distribution of Finnish Heteroptera

We present new records of the flat bug Aradus laeviusculus Reuter, 1875, a near threatened species, in North Karelia, Eastern Finland. Three adult individuals were caught in spruce bark beetle pipe traps during the consecutive time periods of 22.V–22.VI.2006, 21.VII–22.VIII.2006 and 23.VII–25.VIII.2008 at a site that had been burnt for restoration purposes on 7.VII.2005. A. laeviusculus had been considered to be an extinct species in Finland until one specimen was found in Koli National Park in 1996. Here we discuss the possibility that slash-and-burn and restoration burn treatments may sustain the continuum of post-fire habitats essential for the A. laeviusculus population.

“…Eventually Linnavuori ( 1949) confirmed the correction made by Lindberg but at the same time reported one genuine female of E. maurus from Ahvenanmaa, Hammarland, 11.6.1948, as new to Finland. On the basis of this specimen E. maurus has been accepted as a member of the Finnish heteropterous fauna by Linnavuori himself (1967), and later as a consequence by Hulden & Heikinheimo (r984) and Lammes & Rinne ( 1990) as well in their respective catalogues. Dr. Linnavuori kindly lent me his original female specimen from Hammarland, which also turned out to be E. testudinaria.…”

Interesting collection of Corixidae (Heteroptera) from a fish pond

Jansson¹

2000

Altogether 13 species of Corixidae were collected from a drained fish pond in southern Finland in the fall of 1999. Ten of the species had been breeding in the pond, and were thus permanent residents of the habitat. Two species, Sigara limitata and Sigara longipalis, were new to the province of Ta. In taxonomy of the family Corixidae, Glaenocorisa cavifrons (Thomson) is considered as a distinct species because it is sympatric with G. propinqua (Fieber) in Scotland and in northern Finland.
