Don't know if this site will help or not Frenchy but it does have some info about matis'. I remember once about 15 years ago I was sitting outside one night about 10 pm. A whole SWARM of them came at me. Must have been hundreds! They weren't after me. Just moving through the area. Wow! Did I move fast! They actually can open their mouths pretty big. More of a pinch too.
Assumptions do nothing but make an ass out of u and me.
We can stick our heads in the sand for only so long before it starts choking us. Face it folks. The pet population is bad ALL OVER THE WORLD!
