Who can tell me the name?

I find them in Guangzhou, China. They can dig hole. But they can fly in summer. They are about 3cm long. Who can tell me the name of them?

It is eating a small piece of apple in the picture.

Maybe Pycnoscelus surinamensis, that species has been transported by man to most tropical areas.

But I found the wings' color is not so deep in the pictures of surinamensis. Do they have different color?

Some have nearly black wings like P. nigra.

You mean it is more likely to be a P. nigra than a P. surinamsis? Right?
