Keywords: Abstract: In this study totally 55 female samples of (Pompilidae: Pompilidae, Hymenoptera) were collected by an net from different localities in Kars (1850 Anoplius viaticus, m), Kars-Kağızman (Kötek deresi 1400 m) and Kars-Allahuekber Mountains (2800 m). Altitude, Head, thorax and abdomens of the samples were photographed on an electron Cuticle, microscope (SEM) in which their hair covering and cuticle morphologies were Morphology, compared. Bristles on the head, antenna, thorax, and abdomen of the samples were Kars Plateau observed to increase depending on the altitude.

1. INTRODUCTION which can be seen by an electron microscopy (Demirsoy, 1997). Hymenoptera, is one of the largest Members of Pompilidae family have insect order which is represented by 4000-4500 long thorny legs and their bodies are cylindrical species in the world (Day, 1988). Pompilidae shaped (Rodriguez – Jimenez and Sarmiento, family, also known as ‘ wasps’ are 2008). Adults are usually encountered when generally dark colored (Rodriguez–Jimenez they are searching for prey on the ground or on and Sarmiento, 2008) solitary wasps in this the flowers. Female spider wasps generally order. The body cover of consists of a sting and paralyze belonging to single row of cells of the epidermis and a Lycosidae family to provision for their larvae cuticle layer located just above it (Darry, 1979). After that, the female lays one (Wiglesworth, 1974). When it is examined by egg on the paralyzed individual by carrying it light microscopy, it seems as a flat structure to the spider nest which is dug on the ground but actually the cuticle structure is unique to (Coello, 2000). Some of the wasp larvae feed by sucking the prey’s body fluid. Most of the * Corresponding Author: [email protected]

DISCUSSION AND CONCLUSION Hair coverage in the area between the ocelli is intensive in our samples, compatible Cuticular morphology of specimens with that of Jimenez and Sarmiento (2008), belonging to Anoplius viaticus were examined probably because of heat insulation. The for the first time. Since no study was found increase in the distance between the ocelli with Pompilidae family members, the data depending on the altitude conforms to the rules obtained in the study were compared with of James (Rench 1938), which is also defined those of general insect and . as Extended Bergman (1847) rules.
