Although the mitochondrial cytochrome oxidase I (COI) gene has been used widely to detect cryptic diversity and inter-population differentiation in odonates (Brown et al.
Studies in other odonates have suggested that selective pressures such as landscape structure (Taylor & Merriam, 1995), food and predation stress (Svensson & Friberg, 2007), wind and high acidification of the larvae biotopes (Marinov & McHugh, 2010), and sexual selection (Outomuro & Johansson, 2011), can affect the evolution of wing and abdomen characters.
The departments with higher number of odonates species recorded (Table 1), correspond to regions with high level of investigation in the Odonata.
Lastly, there is ample, succinct information on the life history, ecology, taxonomy, morphology, and curation of Odonates in the front matter.
We found that lotic odonates in Illinois were more likely to be uncommon/rare than lentic species, a result also found by Korkeamaki and Suhonen (2002) for odonates in Finland.
Other odonates present were Selysiothemis nigra, which was common, and small numbers of Ischnura evansi, Crocothemis erythraea, Diplacodes lefebvrei, Orthetrum sabina and Trithemis kirbyi.
Considering the classification of aquatic macroinvertebrates by Kruger and Lubezenko (1994), daphnia, stone flies and may flies are very sensitive species, freshwater shrimps are medium tolerant, odonates such as damsel flies and dragon flies are tolerant species, whereas, cleopterans, arachanids, and gastropods are very tolerant.

Odonates were found to be absent at St II while their presence was recorded at rest of the stations in the monsoon period.
