It is another from the series of extremely hot days. But it is time to go out becouse is Oryctes nasicornis season and I dont want to miss it. This Scarabaeid beetle is common here and in this period of year can be found in profusion throught out whole forest. The beetles can be found mainly in sparse forest or in open xerothermic localities with dead Oak trees. The trees must be in sandy soil and must have naked roots. This is the sine qua non for females to lay eggs. Solitary oak trees are the most theratened becouse of another beetle Cerambix cerdo that larvae developed under the bark drive trees to the death. Around this dead trees or tribes lot of Oryctes beetles can be found. Among the beetles there is wide variety in size and the bigger beetles tend to be in the most suitable trees.
