Trying to identifying a bug that has a conical-shaped body. At the head, are two fairly long antennae. The rear of the bug is pointed. The body has grooves width-wise, like stripes; and the insect is charcoal gray.

I'll try to help, but I need some more information.

First, since this is an international site, what part of the world does the bug reside in?

Second, how many body segments are visible?

Third, since you said it is an insect I'll have to assume six legs.

My first guess would be a beetle of some type, but that only narrows the field.

If you could post a picture or a link to one it would help immeasurably.

Midwest United States, Chicago, IL. Six segments are visible, plus end segment and antennae. Legs are not visible, maybe underneath, as assumed. Unfortunately, do not have active drawing art. Unable to locate picture anywhere. Body is size of end nail, fingernail-length. Width is just over 3 mm at widest part. Basically, the same width, slightly wider in center, giving it a conical shape.

Does it look anything like this one, then?

Only 3 mm x 6 mm

Perhaps a young millipede nymph.

The picture sure looks a lot like what is sometimes called a "pill bug" or "rollypolly" because they can curl up in a ball for protection. Not really a millipede, but probably related to some degree.
