I found this bug lying on my porch. I thought that it was dead, and I carefully brought it into my house for photographing. But I think that it is slowly and slightly moving. So maybe it's not dead after all.
What kind of bug is this?

I'm not familiar with them but I suggest it may be an alderfly Neuroptera, Sialidae.

Sorry to correct you, Harold, but that is a fish fly (genus Chauliodes), of the family Corydalidae. The genus differs from its even larger relatives (Dobson flies, genus Corydalus) by the pectinate antennae.

No problem, Harry. I was far from sure.
We don't get either over here.
Judging from a look at internet images, one or two others have made the same error.

Unfortunately, because they are spectacular.
I have seen and occasionally caught Dobson flies in China - the males are intimidating with their huge (though virtually non-functional) mandibles. Their larvae (aquatic), however, are quite fierce biters when teased too much - and they are huge, too.
