As the name implies, the Chernobyl Ant is a very abnormal (but effective) terrestrial.  Its large profile tempts the fish into having a larger meal.  The body is made using a single piece of tan foam tapered at both ends, and it has an underbody of yellow dubbing.  Its two wings are made of Z-lon.  Four pairs of yellow barred legs add realism and movement.
