Ten-lined June beetle

Polyphylla decemlineata

The ten-lined June beetle, also known as the watermelon beetle, is a scarab beetle found in the western United States and Canada. The adults are attracted to light and feed on foliage. They can make a hissing sound when touched or otherwise disturbed, which can resemble the hissing of a bat. This sound is made by their wings pushing down, forcing the air out between their wings and back.

This antennae increases surface area and can be used to detect odors and tastes, possibly even wind speed and direction, heat and moisture.

They are not very smooth fliers but rather clumsy because they barely reach eight kilometers per hour. They are strongly attracted to lights, causing them to bump and buzz against window screens, cover walkways and porches as they roll on their backs with their legs in the air. The most common grasses it feeds upon are Bermuda grass, St. Augustine grass, and tall fescue, all of which are plentiful in the Phoenix, Arizona metro area. Has little human benefit unless you like to fish because they make a great fish bait. Bass particularly find them tasty even in place of traditional worms.

Appearance

They are relatively large in size, some growing to sizes as large as 1.5 inches or more. As in other members of this genus, the males have large distinctive antennae consisting of several lamellate plates, which they close up when threatened. The antennae are used to detect pheromones emitted by the females. The wing covers have four long white stripes and one short stripe each. The underside of the thorax is covered with brownish hairs.
