We used 3 types of traps, and 2 of them are described under the following pictures. The 3^rd one is a trap for necrophagous beetles : dead snake or lezard, put in a half plastic jar, with wire netting above to avoid other animals remove the bodies.

Classical trap for butterflies. Lures are ripe bananas… with 3 drops of rhum.	Trap for dung beetles : put your excrements in linen and let it hang up above half a plastic jar, in which you fill half full with soapy water. (don't try if you have diarrhea !!)
