anthers and stigma ripening together. The stigma serves as an 

 alighting place for insects which bear pollen from other flowers.

anthers add to the attractiveness of the flower. The stamens first 

 bend outwards, while the petals are erect, the ring and stigmas serving 

 as the only alighting place for insects, and pollen is deposited on the 

 stigma, so that the flower is cross-pollinated. The oblique position of 

 the flowers turned to the sun makes self-pollination possible in wet 

 weather, and when insects do not visit the flower. 



The Dog Rose is visited by Heleophilm, Syritta, Mcligethes, 

 Antkrenus, Anthocomus, Cetonia, Phyllopertha, Mordella, Rkagium, 

 Strangalia, Luperus.
