Combee, a honeycomb-shaped bug-type Pokemon, can be evolved into Vespiquen in Pokemon GO.
The evolution process is subtle, with the female version having a triangle on its head.
The "evolve" button is available for a female Combee, allowing it to evolve into Vespiquen.
Vespiquen does not spawn in the wild in Pokemon GO, so a Combee must be caught and evolved to obtain it.
If finding a female Combee is difficult, Lures and Incense can increase the Pokemon spawn rate.
Shiny Vespiquen, a darker, more orange color, can be obtained by catching a Shiny Combee and having it be female.
Shiny odds are boosted during certain events, such as the Bug Out event in Pokemon GO.
