A question please?

What is this ผึ้งกัดใบ? Could you please show pictures, scientific names and other details?

As I know, bees do not have 'teeth' and so cannot bite off any thing. Bees have suction tubes to drink nectar and water. Bees collect pollens with their hairy hind legs. These facts may be obsolete --old--. Your latest facts would improve this. Thank you.
