Every morning, i am seeing some wasp fly and sit near water then drink water sip by sip. I think everyday like what wasp drink water, how it is possible?  Actually true is YES, but not that way.

Wasp does not drink water only for thirst instead they used for many purposes.

1. They use for mix water with wood pulp to make their nest.

2. Use water for cooling their nest in hot days.

3. In summer days, wasp often stand near water and drenched for hydrated body when it's very hot and dry. When wasp is drench carefully without drenched wings.  If wings drenched they will not able to fly. Now you can think, yah wasp are absolutely amazing. 

4. And also share water to nest mates and larvae.

How are they share with nest mates and larvae?

First they collect water through mouth and swallow it. Then bring up into other wasp mouth. This process is called Trophallaxis. Wasps are Very friendly.

Now we can understand why they drink water.
