Empirical work has found that, in odonates
, copulating pairs are more vulnerable to predation than are single males (Fincke, 1982), and in a semiaquatic bug, Microvelia austrina, the proportion found in copulation is lower when there is a predator present (Sih, 1988).

This framework agreement includes cash inventories and detailed benefits as follows: - habitats and flora, - terrestrial mammals, - bats, - breeding avifauna, - wintering and migratory avifauna, - reptiles, - amphibians, - insects including lepidoptera, rhopalocerans, Odonates
, orthoptera, ichthyofauna (freshwater and seawater) and invertebrates of harbor water plans, - seabed benthos at different sites, - overall ecological quality assessment, - biological monitoring of habitats - the identification of wetlands and their functionalities, - the ecobanks linked to the inventories of biodiversity in the port territory.
Bionomic differences in odonates
and their influence on the efficiency of indicator species of environmental quality.
are ecologically important as both predators and prey.
With only a few exceptions, odonates
do not exhibit much intraspecific color pattern variation that is clearly correlated with geography despite distributions that encompass several ecological niches and wide areas.
The list of susceptible invertebrates includes bivalves, odonates
(dragonfly nymphs), polychaete worms, isopods and amphipods, decapod shrimps and crabs, as well as native gastropods (Appleton et al.

were collected from the shoreline around the pond by use of a large aerial net and identified using regional texts (Curry 2001; Glotzhober & McShafirey 2002).
In addition it has been proposed that this variation, might respond for the strong differences in the capability of wing flexion among some odonates
such as Aeshna Fabricius, 1775 and Pachydiplax Brauer, 1868 (Combes & Daniel, 2003).
This situation reflects that the study in the taxonomy of the odonates
in Colombia is still emerging, since it is a low number when compared with other countries of the region such as Peru (481 spp.
were consistently among the lowest groups represented.
