You can try this, get a 1/8" ID metal tube, put in you drill and punch out a plug. Cut a 45 deg. on each end so they are perpendicularl. I'm am going to assume you are right handed, tie in one end slant side up with the body over the eye of the hook. Bring it back over the hook (you can slit the body if you like and superglue it to the shank. If you do lay down a coat of thread) A bout 1/8' back tie a head and 1/4" back, or whatever looks good to you, tie the thorax, add legs. Tie off. 1/4" just makes a larger bug.
