This little guy is almost cute until you know it’s a blow fly drawing. While they are considered occasional pollinators, these insects generally prefer scavenging carrion and dung.
I found him in an article about flying and flight that compared the wing structure of animals that fly through the air and underwater. When this fly is in flight, the wings create a pattern that stretches the entire length of each side of its body.
This black and white blow fly drawing is from the 11th edition encyclopedia. It’s contents are in the public domain while it’s name remains under trademark.
