Tiivistelmä

1. Natural wetlands are among the most threatened habitat types world-wide. They contain a high diversity of macroinvertebrates, including dragonflies anddamselflies (Insecta: Odonata). In agricultural landscapes, new wetlands have been con-structed tofilter nutrients and solid matter from agricultural runoff. These types of wet-lands may also benefit Odonata as new breeding habitats. However, it is not yet clearwhat environmental characteristics of constructed wetlands are important for Odonata.
2. We studied 20 constructed agricultural wetlands in Central Finland and askedwhether Odonata are able to use these wetlands as breeding habitats, and which environ-mental characteristics (aquatic vegetation, water area, shoreline length, bottom typediversity, water transparency, and pH) of the wetlands affect odonate abundance and spe-cies richness.
3. The constructed wetlands hosted altogether 17 odonate species. Odonate abun-dance was positively associated with the number of aquatic vegetation growth forms ofthe wetland. Odonate species richness was associated positively with abundance,floating-leaved vegetation, and water transparency.
4. Constructed agricultural wetlands support local diversity of common odonate spe-cies. Although protecting the remaining natural wetlands is of primary importance, con-structed wetlands can add suitable wetland habitats in the agricultural landscape. Fromthe perspective of Odonata, heterogenic aquatic vegetation and water quality are featuresworth promoting when constructing and managing agricultural wetlands.
