Phenology of aquatic insects in a protected wetland (Natura 2000 network) in northwestern Spain
The aim of this study was to gather new data about the life cycle phenologies of several species of aquatic insects in the "Gándaras de Budiño" (Galicia, NW Spain) protected wetland, included in the Natura 2000 network. During an annual cycle (2004-2005), three shallow lakes and four strea...

| Resumo: | The aim of this study was to gather new data about the life cycle phenologies of several species of aquatic insects in the "Gándaras de Budiño" (Galicia, NW Spain) protected wetland, included in the Natura 2000 network. During an annual cycle (2004-2005), three shallow lakes and four streams were sampled monthly using a semi-quantitative sampling method. The body lengths of the larvae and nymphs of thirteen species were measured, and their life cycles were analysed. All species had univoltine or semivoltine cycles. Additionally, a possible correlation between larval and nymphal lengths and water temper ature was examined. We found a significant correlation for two species: the water beetle (Note rus laevis) and the dragonfly (Boyeria Irene). It is important to highlight the presence in the studied area of a species included in the Habitats Directive: the damselfly (Coenagrion mercuriale). |
