This is a photo of a wasp standing on top of the water in a pool to drink. It is able to do so because of the property of surface tension. The like molecules at the surface have a cohesive force strong enough to resist the external force of the weight of the wasp.
This is a high quality photograph for personal, commercial or educational use.
This picture was taken by me so you can be confident that it is approved for commercial use in your TpT resource.
The photo you download will not have a watermark on it.
