Thank you Paolo,
I live on the southern outskirts of Prague in a small family house.We have three large shrubs
Campsis radicans, they grow like weeds, every year, cut the branch length 120 cm.I only reach a height of 2 m,above must be alive.Before I drove hundreds of kilometers per insect,now two years sitting in the garden and I have a better catch.Even rarities Apis,wasp,Chalcids.I never knew that the house is such diverzibilita.....
