Flower chafer

These young beetles strangely choose to do their own part of the plant infestation in the dark. One by one, they flew in like invaders from another realm. That was the very first time I noticed them on the citrus tree. They took off once they had their fill.
In this case, I'm assuming these are offsprings of the adult beetles seen here about two weeks ago. They formed clusters on the flowering heads. It is quite obvious that this is the new generation they left behind to continue their abominable mission. (Photos of the adults were uploaded previously)
