Observations on a gynochromatic (?) male of the dragonfly, Rhodothemis rufa (Rambur, 1842) (Odonata: Libellulidae)

The Dragonfly Family Libellulidae (Insecta: Odonata: Anisoptera) of Shiraz and its Vicinity (Fars Province, Iran)

Thirteen species in five genera of the Libellulidae family were collected in a survey of dragonflies (Odonata) of Shiraz and its vicinity, involving 19 locations, The presented records of the libellulid dragonflies taken from the Fars province comprise a first time collection of two genera, Sympetrum and Pantala, and seven species, Orthetrum anceps Schnider, Orthetrum taeniolatum Schneider, Ort...

new records of rhodothemis rufa (rambur, 1842) and lamelligomphus biforceps (selys 1878) (odonata: anisoptera) from pakistan with redescription of l. biforceps (selys 1878)

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...

Impact of cuticle photoluminescence on the color morphism of a male damselfly Ischnura senegalensis (Rambur, 1842)

In this study the damselfly Ischnura senegalensis (Rambur, 1842) was first found to produce strong photoluminescence (PL) emissions from various colored-body portions, such as the eighth abdominal segment of the tail. The colors of the colored-body portions can be enhanced or modified by the PL emissions for assistance in reducing intrasexual and male harassment, and improving mature mating and...

Proximate constraints on intruder detection in the dragonfly Perithemis tenera (Odonata: Libellulidae): effects of angle of approach and background

The implications of insectsÕ vision for territorial defense have been relatively little studied in the Þeld. In the dragonßy Perithemis tenera Say we investigated whether either the angle at which an intruder was viewed by a territorial resident or the background against which it was viewed affected the detection of that intruder. Residents detected intruders at a greater distance if the intrud...
