Figure 16. A distribution of Leucorrhinia pectoralis in Latvia in the 5x5 km square grid. The data on L. albifrons habitats were obtained from 130 water bodies, on L. caudalis from 97 water bodies and on L. pectoralis from 160 water bodies. L. albifrons was mostly found in dystrophic lakes, L. caudalis in eutrophic lakes, but L. pectoralis in oxbow lakes (Table 10). From 55 surveyed oxbows of the Gauja river L. albifrons was found in 2 oxbows, L. caudalis – in 14 oxbows and L. pectoralis – in 36 oxbows. Table 10. The Leucorrhinia albifrons, L. caudalis and L. pectoralis selected habitats in Latvia. Species Mesotrophic lake Leucorrhinia albifrons 13 (10 %) Leucorrhinia caudalis 6 (6 %) Leucorrhinia pectoralis 7 (4 %) Eutrophic lake 41 (32 %) 49 (51 %) 41 (26 %) Dystrophic lake 62 (48 %) 16 (16 %) 40 (25 %) Pond Oxbow Other 4 (3 %) 5 (5 %) 9 (6 %) 2 (2 %) 17 (18 %) 51 (32 %) 8 (6 %) 4 (4 %) 12 (8 %) During the study of 2005 in Tītmaņi oxbow, L. albifrons was found in two surveys in one sampling plot (three individuals), while L. caudalis was found in one survey in one sampling plot (one individual). L. pectoralis was found in six surveys in eight sampling plots (total 70 individuals). The greatest number of individuals was found in sampling plots with open water pools and little shading (up to 30 %; No. 1, 2, 3, 4, 7). The dominating plants in these sampling plots were Menyanthes trifoliata, Stratiotes aloides, Glyceria fluitans, Carex nigra and Equisetum fluviatile, except for one sampling plot (No. 4), where Agrostis tenuis predominated. In two sampling plots (No. 5, 8), L. pectoralis was not found. 66
