Botswana 5 Pula Mophane Worm!

Minted only in 2000, this coin is the only one I know of which features a caterpillar! On the obverse the coin bears the National Coat of Arms and the words "Botswana Ipelegeng" and the year 2000. On the reverse, the coin bears an image of a "Mophane Worm" (Gonimbrasia Belina) feeding on a Mophane Leaf and the denomination '5 PULA' written on top.
