Table 2. Potential southern species for the fauna of Latvia and presence of each species is indicated
for the adjacent countries – Estonia (EE), European part of Russia (RU), Belarus (BY) and
Lithuania (LT). For each species the approximate distance (D) in kilometres to the nearest foreign
locality and the source of this record is given.

Species distribution changes. According to zoogeographical classification (Udvardy 1975;
Taglianti et al. 1999; Крыжановский 2002), species with Palearctic and West Palearctic
distribution type are mainly represented in dragonfly fauna of the Latvia. Only 15 % species have
Holarctic distribution (Figure 2). Exceptions are Mediterranean-Afrotropical species Anax
ephippiger, West Palearctic-Afrotropical species Anax imperator and Mediterranean-Palearctic
species Sympetrum fonscolombii.

Figure 2. Zoogeographical classification of the dragonfly species occurring in Latvia.
The data was collected from 839 squares that constitute 30 % of all squares covering Latvia (Figure
3). The quality of the data is diverse. This is reflected in the number of species recorded within one
grid square (Figure 4). For 53 % of the studied squares the quality of data is low as the number of
recorded species does not exceed 5. The data is qualitatively moderate (6-10 species / square) for
