Here is a foam hopper that can be modified for a cricket pattern by just changing the colors. It is tied like a Stealth Bomber except the foam over body is pulled snug and the head foam is cut straight without the V shape of the Stealth. The under body would be black floss. The rear leg is a doubled piece of rubber/silicone with an overhand knot which has one of the tags clipped off at the leg joint. A dab of super glue is applied at the knot joint of the leg to prevent it from untying.
