what are the life stages of a dragonfly Dragonflies are hemimetabolous insects; they do not have a pupal stage and undergo an incomplete metamorphosis with a series of nymphal stages from which the adult emerges. what are they ? It is an insect belonging to the order Odonata, infraorder Anisoptera. any conservation efforts to protect it ? In 1997, the International Union for Conservation of Nature set up a status survey and conservation action plan for dragonflies. talk about their coloration ? It is often a combination of yellow, red, brown, and black pigments, with structural colours. what are its behavior patterns ? Many dragonflies, particularly males, are territorial. Some defend a territory against others of their own species, some against other species of dragonfly and a few against insects in unrelated groups.
Male to female dragonflies varies both temporally and spatially, adult have a high male-biased ratio at breeding habitats The sex ratio of male to female dragonflies varies both temporally and spatially. Adult dragonflies have a high male-biased ratio at breeding habitats. The male-bias ratio has contributed partially to the females using different habitats to avoid male harassment.

Dragonfly [SEP] Sex ratios
The sex ratio of male to female dragonflies varies both temporally and spatially. Adult dragonflies have a high male-biased ratio at breeding habitats. The male-bias ratio has contributed partially to the females using different habitats to avoid male harassment. As seen in Hine's emerald dragonfly ("Somatochlora hineana"), male populations use wetland habitats, while females use dry meadows and marginal breeding habitats, only migrating to the wetlands to lay their eggs or to find mating partners. Unwanted mating is energetically costly for females because it affects the amount of time that they are able to spend foraging.
