1 Introduction

Robber flies(Diptera: Asilidae)comprise a large and widespread family of insects. The adults are often active flies of considerable size and readily attract attention(Geller-Grimm,2005). Asilid adults attack insects of almost all orders, from wasps, bees, and flies to dragonflies and grasshoppers; even some spiders are eaten(Lavigneetal.,1978;Lavigne,2003). Robber flies can be regarded as a beneficial group of insects. However, it was also noted that they are enemies of honey bees and are commonly found around bee hives destroying large numbers. Some species, especially the smaller ones, do not catch their victims in flight, but await small insects which, by chance, fly within their reach. At any rate we are unaware of any robber fly which is not a predator(Hull,1962;Theodor,1980;Bosák and Hradsk,2001).

Golestan province is located in the north of Iran and south of the Caspian Sea. Geographically, Golestan is divided into two sections, the plains and the mountains of the Alborz range. In the eastern Alborz section, the direction of the mountains faces northeast and gradually decreases in height. The highest point of the province is Shavar, at 3,945 m above sea level. Golestan climate is temperate for most of the year.

The fauna of Iranian Asilidae has been studied rather well by several authors(e.g. Abbassian-Lintzen,1964a,b;Lehretal.,2007;Hayatetal.,2008;Ghaharietal.,2007a,b,2008a,b,2009,2010;Saghaeietal.,2008,2009,2010;Sakeninetal.,2008a,b,2009,2010,2011;Tomasovic and Saghaei,2009;Saminetal.,2010,2011;Ostovari and Rastegar,2013). The aim of this paper is faunistic survey on Asilidae in Golestan province.

2 Materials and Methods

For studying the asilids' fauna of Golestan province, many samplings were conducted at different localities of this province. Identifications made by Engel(1930), Oldroyd(1958), Abbasian-Lintzen(1964a,b), Tsacas(1968), Theodor(1980)and Lehr(1988). The taxonomic arrangement and distributional data for regions outside Iran are those of Lehr(1988,1996), Bosák and Hradsk(2001)and Geller-Grimm(2005). The information concerning specific name, describer and description date, locality and date of collection, place where the species were collected, determinant and number of species was given.

4 Discussion

This research shows that there is a diverse fauna of Asilidae in Golestan province, Iran. Among the 21 collected species, 9 species belong to subfamily Asilinae. Of course we did not sample all the regions of the mentioned area and continue to sampling in other regions especially in Golestan National Park surely will result to new data. Asilids are powerful predators of insects and other arthropods but the prey - predator relationships was not studied very well about them. One of the most interesting topics for the researchers can be this valuable subject.
