find three types of Beetles and insects in different places

Hello insect friends, meet me again @asklanbudi, on this occasion I would like to donate some photos of insects that I found in different places and different shapes.

This first beetle I found in one of the tropical forests in Aceh, North Aceh, Indonesia to be exact.
I accidentally crossed this forest area and I saw a small beetle standing on a leaf, long story short I took some photos using a tool or lens to shoot a small beetle.
Friends can find out about the beetles that I share.Chrysolina bankii

This beetle that I found, I found a few weeks ago in my friend's yard, This beetle is the size of an adult human big toe, it's gray, I can't take many photos, I approached this beetle, he was a bit annoying, I can only take some of my shots. Friends learn about this beetle through the web that I shareMelolonthinae

Meet this attack that no one cares about. This attack is again making love to fellow lovers, he seems to forget that someone is approaching him.
This attack I found in the same place that is at my friend's house, I was only able to take a few shots with me and helped with the lens, because this insect is a little smaller in size.
Friends can see it in my post below, about this attackPolybia occidentalis

Thank you, insect friends who have visited my account, I hope you like it. Greetings from me @asklanbudi🙏
