Mournful sphinx

The mournful sphinx (Enyo lugubris) most likely gets its name from the somber colors that make us think of a desert environment, with deep, dark browns. Other people think that it may be related to its droopy posture, but this is just speculation. The insect is also attracted to lights, meaning it flies and is difficult to spot during the nighttime.

Spurge hawk-moth

The spurge hawk-moth (Hyles euphorbiae) earns its name from being a biological control agent of leafy spurge, which is considered to be an invasive plant. It lays eggs on the leaves of these plants, covering them in what has been called a "liquid gum" substance that keeps them sticky. Adults are brown and pink while the caterpillars are smooth and black.

White-Lined Sphinx

The white-Lined Sphinx ( Hyles lineata) is a colorful furry moth with striped wings. It has a similar size of a hummingbird, and behaves like a hummingbird as well. It can fly extremely fast, and instantly swing from side to side while hovering just like a hummingbird. It feeds on nectar from a variety of flowers including petunia, honeysuckle, lilac, clovers, thistles, and jimson weed.

Bedstraw hawk-moth

The bedstraw hawk-moth (Hyles gallii) flies throughout the night in search of meadows and mates. Their main caterpillar host, bedstraw, is where it gets its name. Otherwise, they are a beautiful combination of tan, red, and darker streaks of color. They enjoy living in warm locations, such as nearby plantations.

Southern pine sphinx

The wingspan is 50–57 mm. The forewing is grey with two or three black stripes in the middle of the wing. Other marking are vague.
