That is exactly what this is. :)
See those two black pin-point spots near the front? Those are its 'eyes', if I'm not mistaken.

It's a nice photo, though, as you've already pointed out it, sadly, doesn't belong here. :(

predator of, among other things, insects, maybe with the gnat? It's interesting enough!

Whatever it is, it's the same as the one you found. They can climb, since this was 5' up on the house siding under the porch light. Thanks Lynette.

I'd be willing to bet it is a flatworm in the family Rhynchodemidae. They are predaceous on other invertebrates. One noteable species is Platydemus manokwari that was introduced into a number of island habitats to control Giant African Snails. Unfortunately, they also took a liking to native snails and slugs, resulting in reduced populations and the threat of extinction for the natives. It is noted that the head end is the pointier of the two. You can clearly see the eyespots on the pointed end in your picture.
