In Pokemon Go, I'd like to know if certain Pokemon that appear at night, by category such as ghosts, bat Pokemon Psychic type Pokemon, power plant Pokemon, etc, appear at differrent phases of the night, such as civil twilight, nautical twilight, astronomical twilight, full night, and certain Pokemon appear at different times a day, such as the afternoon, or late-morning around 9 am, Pokemon categories such as grass Pokemon, forest Pokemon, etc. I also would like to know whether what Pokemon appear is partly decided upon by habitat or seasons, or time of year not just seasons. (Ie ghosts in October, Jynx and Lapras around Christmastime, etc. for time of year, household Pokemon, park Pokemon etc. for habitat, ice Pokemon for winter, and grass type Pokemon for spring and summer, and weed Pokemon, such as the Oddish line appearing in the fall, for seasons. An example of night Pokemon appearing at a certain phase of the night, for example, is, and this is randomly theorized, and not necessarily true, bat Pokemon appear at nautical twilight. Power plant Pokemon appear in households at full night, for a more precise theory.) Any help?
