AbstractBehavior study of mud dauber wasp S. caucasicum showed that the adults spend their hibernation beneath the falling leaves in fields nearby buildings from the early November till the end of February and returned to build their solitary nests in grouped cells with an average of 7.5 – 14.5 cell/ nest from March till the Middle of October and laid one egg per each cell. The results of 506 nest inspected from September 2008 till August 2009 revealed that the females builds 1 – 21 cell and single cell in 104 nests. The females of wasps collect orb weaver spiders and lepidopterous larva from the plants to fed the larva of wasps after hatching , variation appear in kind and number of the preys and reached 1 – 45 individual/ cell. The orb weaver spiders are available during the following months ( September, October, November and December, 2008 & also in January, February, May, June, July and August, 2009. A significant positive correlation appeared between wasp larva and their preys with temperature and non- significant negative correlation with relative humidity.
