As others have reported and now that LeekDuck, one of the most reputable sources when it comes to Pokemon Go has confirmed that Shiny Scyther is now available in the wild! Its a Pokemon that’s on the rare side but thanks to the current increased spawn rate for Bug types, you ought to see it popping up more often.
Also, you can find it by completing the Field Research Task “Catch 10 Bug-type Pokemon” where the upside is that the IV of encountered Scythers will have a higher chance of having a good IV value as opposed to ones caught in the wild. The downside of this is that all Pokemon from Field Research Encounters are level 15 while those in the wild go up to level 35 depending on the weather conditions.
All the more reason to get out there and hunt for Bugs in the latest event!
