Just a quiuck note. Where did your son find the green insect? It coulb be posible that it at one point ate oir was near a plant that was sprayed with some sort of pesitcide. This is why I do not go out and catch my lizards food, Even though I can catch enough food and never spend a dime on it I can not garontee my neighbors didnt spray there yard with bug killer or somthing.
