so beautiful bug-6: Japanese beetles

Summer is the season when bugs rule the world. ^^

The bugs shown below are called Japanese beetles.  They are abundant particularly in June.
They are about 1/3 inch long and indigenous to Japan (Duh!).

According to the record, they seemed to immigrate into North America in early 1900's.  Because of no natural enemies, North America has been their paradise.

The two on the left are 열애중 in broad daylight. 차아식들... ㅋㅋ.   Male is piggybacking female.  In insects, the females store sperms in their body and fertilize eggs. So until all sperms are used, females are refractory to mating again. 

They have metallic green pronotum and brownish elytra.  They are marvelous but a headache for gardeners (devilish beauty?).

In June, the beetles infest trees and vegetables heavily, grazing leaves; some of you might have seen them in your valuable fruit trees. ㅠ|ㅠ.

So the battle begins. How?
Actually it is kind of fun to kill them.  An interesting behavior is that the beetles fall down directly to the ground when they are threatened even slightly.  This is perhaps their tactic to escape from enemies.

Hmm. OK.  So I prepare a pan filled with soapy water, place it under, and then disturb the beetles a little.  Then they drop into and get drowned under the soapy water (Drop Dead!).  There is no way they evolve 'resistance' to this kind of 'bugcide'.  Ho Ho.

Japanese beetles belong to 'Order Coleoptera; Family Scarabaeidae'.
