Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
When this card is Normal Summoned: You can Special Summon 1 Level 4 or lower Insect monster from your hand. You can banish 1 Level 4 or lower Insect monster from your hand, GY, or face-up field, then target 1 face-up monster you control; increase its Level by the Level of the banished monster, until the end of this turn. You can only use each effect of "Dragonbite" once per turn.
