Find all the butterflies - and there is a mosquito in the jar.

I can't find the last butterfly. When I hit the "hint" it clicks on the mosquito in the jar, but I don't know what to do. Can anyone help me?

Thanks.

JennyPenny, you've probably moved past this one. But, if not, there's either a butterfly etched into the glass of the jar or on the lid. Happy Gaming.

Thanks. With your help, I found it.
