The other day Fred Hannie of Realistic Fly Tying posted this image on his Facebook page and I asked him if I could share here as well. For reference this beetle is tied on a size 18 hook. I find his fly tying to be really quite amazing.

Just about any bug found near a fishing spot is just one sudden gust of wind away from ending up on the menu . Apart from the many aquatic species and terrestrials that we tie to imitate are a variety of garden insects that appear in numbers large enough or often enough to make inclusion into the fly box.
The Spotted Cucumber Beetle has a size and color that make it an attractive fly to both fish and fishermen. I used 6/0 white thread and monofilament in 40 pound and 10 pound for the body . 4M monofilament thread was used for the antennae and legs . The coloration was done with permanent markers and the thread was sealed with a flexible head cement."
