"Primitive Butterfly" is a Normal Summon monster.
The monster effect "①: If you control no monsters, you can Special Summon this card (from your hand)" is an effect that is not classified as an Ignition Effect, Trigger Effect, Quick Effect, or Continuous Effect. (A Chain Link is not created when Special Summoning this way.)
The monster effect "②: Once per turn, during your Main Phase: You can increase the Level of all Insect-Type monsters you currently control by 1" is an Ignition Effect. (This effect does not target. It is also applied to "Primitive Butterfly" itself while it is face-up on your field.)
The Level increased by this card's effect remains applied as long as that monster remains face-up on the field. (The Level remains increased during the following turns as well.)
