@suzana72, thats actually a good advise from one of a masters of macro photography here on Hive: get up at 5 oclock in the morning when all the insects are cold-blooded and thus retarded and slow, even not slow but motionless! and you can approach them and do what you want, you'll have a time for tripod, rails, focus stacking... of course if you will find someone! biodivercity in my area is not that great like you have in Serbia, so personally, I get up early in the morning to find nobody around :))
PS. cold weather also can help.
all the best!
