the current status and distribution of the dragonflies (anisoptera) of pakistan were studied during 2005-2009. two dragonfly species were identified for the first time from pakistan. among these, rhodothemis rufa is a red, medium-sized dragonfly. lamelligomphus biforceps is also reported for the first time from pakistan and re-described owing to having minor taxonomic differences from that of f...

This study compared the predatory potential of nymphs two dragonfly species viz. Crocothemis servilia (Drury, 1773) and Rhyothemis variegata (Linnaeus, 1763) using different larval instars pupae Cx. quinquefasciatus (Say, 1823) as preys in normal laboratory settings. Field-collected fed 24 h starved C. R. were offered 1st, 2nd, 3rd 4th instar larvae to monitor rate predation. A nymph showed hig...

To study the accumulation and contamination of heavy metals (i.e., Cd, Cr, Cu, Ni, and Zn) in soil, air, and water, few insect species were assayed as ecological indicators. Study area comes under industrial zone of district Gujrat of Punjab, Pakistan. Insects used as bioindicators included a libellulid dragonfly (Crocothemis servilia), an acridid grasshopper (Oxya hyla hyla), and a nymphalid b...

Dragonflies are the bio indicators of the aquatic ecosystem. Knowledge and studies on the diversity of dragonflies in India is very high. Identification by traditional taxonomy often leads to misidentification. Incidence of sexual dimorphism is found to be high particularly in the Libellulidae and Aeshnidae family. In order to resolve the above mentioned problem, the accurate identification of ...
