Are japanes flying beetles very bad?

So i have a grow and i got a bunch of lady bugs that are commin in and im throwin them in my box, but i found out today they're probably japanese flying beetles since oklahoma doesnt have traditional lady bugs.. just i get rid of them.. they dont seem to be harming the plant, but u never know

Didn't they bomb Pearl Harbor?

LOL, just kiddin.

Lady bugs are helpful, but Jananese Beetles are bad.

BAHAHAHAH LMFAO... Thanks man.. ya im pretty sure they're flying beetles so time to start plucking

Yes, they can do great damage. They are very hungry little bastards.

What color and size are they?Ladybugs fly you know.Japanese bettles are green and brown.They can grow to about the size of your thumbnail.

If you're talking about Asian Beetles (see pic), they are not harmful to plants - they eat nematodes. Almost as helpful as a Lady Bug - only they pinch, so don't touch 'em too much.

Yeah, the japanese flying beetles that came up on google didn't look anything like ladybugs. Most ladybugs you see nowadays are the introduced asian/japanese ladybug (they have a few common names), which isn't harmful. Here is a list of ladybug beetles (family Coccinellidae) in Oklahoma, in case you are interested--there are quite a few! The asian ladybird beetle (Harmonia axiridis) is in there, which is what DoeEyed posted a picture of.
