Osphranteria coerulescens, a species widely distributed in Afghanistan, Iran, Iraq, Pakistan and Turkey, has been described from South Iran by Ludwig Redtenbacher in 1850 [❖]. Larvae of this beautiful Cerambycid feed in living twigs and branches of various Rosaceae and ocassionally when too abundant can cause serious damage to fruit trees. The adults emit a characteristic scent probably serving as a chemical defence used by the beetles to protect themselves against would be predators such as insectivorous birds. The biology of the species was in detail described by S. Sharifi, I. Javadi and John A. Chemsak in 1970 [✮].

Body length:15 - 25 mm
Life cycle:1 years
Adults in:May - July
Host plant:Rosaceae (Prunus spp., Malus×domestica, Pyrus communis, Cydonia oblonga, Rosa spp. etc.)

The depicted mounted beetles were collected in: ♂ - Kākān (كاكان) village environs (Dinar Mts., Simakan district, Jahrom county, Fars province, Iran) on July 14-16, 2008; ♀ - 15 km W of Kākhk (کاخْک) town (N34°09′ E58°28′; 2100 m a.s.l, Kakhk district, Gonabad county, Razavi Khorasan province, Iran) on May 28, 2008.
