Biology:Diplacodes

From HandWiki

Diplacodes is a genus of dragonflies in the Libellulidae family.[1] They are commonly known as perchers. Their colours range from the totally black body of the African Diplacodes lefebvrii, the lovely pale blue of India's Diplacodes trivialis, to the intense red of the Asian–Australian Diplacodes haematodes.

Various species of this genus occur in Africa, Asia, Australia and the South West Pacific. They are generally small in size.

Etymology

The genus name Diplacodes combines Diplax, a genus name derived from the Greek δίς (dis, "twice") and πλάξ (plax, "flat and broad"), with the Greek suffix –ώδης (-ōdēs, "resembling" or "having the nature of"). The name refers to the similarity of the genus to Diplax and Diplacina.[2]
