Accuracy of map:

Map was created using a map to the scale of 1:40,000,000, using information taken from literature, and by analyzing the collections of the Zoological Institute, Russian Academy of Sciences.

Basic contents:

Vector map. Area of species distribution is shown by polygons. Zones of recorded mass outbreak are shown by polygons.

Accuracy of classifier:

Within the area of distribution, the extent of damage caused to agricultural plants resulted in a zone of low pest damage only, in which 1-6 adults per sq. m occur in spring on clover crops, which, on average, damage about 10-50% of flower heads.

Method of map production:

Scientists were given maps showing the boundaries of Oblasts and arable lands. After reviewing historical literature, species distribution was hand-drawn on maps. If data were on the Oblast-level, distribution is on the Oblast level. In some cases, Oblasts were further refined by boundaries of the Arable Land Map (Koroljeva et al., 2003). Hand-drawn maps were scanned, georeferenced and vectorized. The distribution area was determined according to the following sources: The insect collection of the Zoo. Inst. of Russian Academy of Sciences, and Bobrinskii et al. (1969). The borders of the zone of low pest damage were determined according to the following publications: Vasiliev (1936), Solodovnikova (1970), Dieckmann (1977), Makarov & Shorokhov (1986). The zone of low damage includes the major European part of the former USSR north of the steppe zone.
