Lähde: 

First ones of this family are hatching now. Among these come size 12-14 olive mayflies. We are expecting good falls of spinners, dark olives and rusty ones. A lot of stoneflies are hatching too like family Perlodidae.
A little bit later we are waiting for massive Baetidae hatches.
Some Caddis start to hatch too like Brachycentridae family Micrasema genus and Brachycentrus genus.
So guys, grease your leaders and tippets. Prepare for a perfect cast. Enjoy the great Läsäkoki nature.
