A long horned beetle of some sort. Possible a Long Jawed Longhorn Beetle (Trachyderes mandibularis).

Is it a pest?

It is my understanding that they lay eggs on decaying wood and the larva bore into it. Maybe someone will come along with some more knowledge on this guy. I have seen them in my log piles, but not on living trees. I hope we get some more info.

I read someplace that they are a pest if you have any kind of malpighia or figs.

There are, of course, non-native longhorned beetles with enormous destructive potential in our woodlands. Here I'm talking about specifically Asian longhorned beetle. But luckily, this isn't that, and there are numerous native species with much less damaging potential. I'd have to get my giant bug book out to figure this out but I wouldn't doubt sharon's florida is right on the money...or at least close. Probably no big deal.
