Sure they are!
If, by chance, the water strider did break the water tension and take a plunge, it would not be able to dry off with a bug-sized towel. At this size, surface adhesion forces (van der Waals force) would keep the towel stuck to the water strider
Besides, the water strider could put on a bathing suit for it's dip; and it would never have to worry about the suit coming off when it hit the water during a high dive. First, because its so small, the water strider would float gently down because the frictional forces acting upon the water strider’s surface overcome the weak influence of gravity at this size. Also adhesion forces would keep the suit on the strider for life.
It would also be impossible for the bug to read a book by the pool, since once the pages were scaled down to bug-size, surface adhesion would keep the pages stuck together.
