Cotinis mutabilis, also known as the figeater beetle (also green fruit beetle or fig beetle), is a member of the scarab beetle family. It belongs to the subfamily Cetoniinae, comprising a group of beetles commonly called flower chafers since many of them feed on pollen, nectar, or petals.[1] Its habitat is primarily the southwestern United States (including California[2]) and Mexico.[1] Figeater beetles are often mistaken for green June beetles (Cotinis nitida) and occasionally Japanese beetles (Popillia japonica), which occur in the eastern US.[1]
Figeater beetle larvae, commonly called "crawly backs",[3] roll on their backs and propel themselves upside down. Adult figeater beetles grow to approximately 1.25 inches (3.2 cm).[4] They are a semi-glossy green on the top and a brilliant iridescent green on the underside and legs.[4] They are active during daylight hours, often congregating in the shade of trees near choice breeding grounds to find mates.
The figeater beetle is native to moister areas of the American southwest, where its natural diet includes fruit from cacti and sap from desert trees.[1] Their range has expanded considerably since the 1960s with the increasing availability of home gardens, compost piles, and organic mulch.[1][4] The larvae eat decomposing organic matter, such as that found in compost piles, manure piles, and organic mulch, and occasionally plant roots, such as the roots of grass in lawns.[1][4] The adult's primary food has become fruit in gardens and orchards.[1]
After mating, eggs are laid in decaying matter or compost piles, which provide sustenance for the emerging larvae. Figeater beetle larvae, commonly called "crawly backs",[3] grow up to 2 in (5.1 cm) and are thick and white with a dark head. They have six small, ineffectual legs; to move, they roll onto their backs and propel themselves upside down, using the stiff dark hairs on their backs to gain traction. At rest, they curl into a firm C shape.
Pupation occurs in the spring; adults emerge from July to September (varies with location). Adult figeater beetles grow to approximately 1.25 inches (3.2 cm).[4] They are active during daylight hours, often congregating in the shade of trees near choice breeding grounds to find mates. They make a loud buzzing sound similar to that of carpenter bees, possibly because they do not need to open their elytra in order to fly, an ability shared with many other flower beetles.[1]
C. mutabilis is often confused with the green June beetle (Cotinis nitida).[1] Both are members of the flower beetle subfamily[5] (Cetoniinae), and are similar in appearance, but the green June beetle is smaller, and its range is in the eastern United States. The only possible crossover of both species is in Texas. They are also occasionally mistaken for Japanese beetles (Popillia japonica), which occur in the eastern US.[1]

The adult's primary food has become fruit in gardens and orchards.[1] They prefer sweet food, which includes the leaves, flowers, and saps of some plants and ripe or overripe fruit.[1] Fruit with tough skins are too hard for them to bite through,[1][4] so they most often eat softer-skinned fruit such as figs, peaches, grapes,[4] pears, and tomatoes, among others.[1] The beetles are particularly attracted to ripening and fermenting fruit, which emit gases that lead the beetles to them,[1] and to fruit that other animals or insects have already damaged.[1] In most small gardens, the adult beetles are minor pests that do little damage; however, they can swarm on soft or damaged fruit and have been known to eat an entire garden grape or fig crop.[1] They are not considered to be an important pest because they do not damage lawns as larvae and trees as much as June beetles or Japanese beetles.[1][4]

El mayate (del náhuatl máyatl) escarabajo verde de junio o pipiol, Cotinis mutabilis, (no confundir con C. nitida que tiene aspecto similar) es un coleóptero polífago de la familia de los escarabeidos (Scarabaeidae). Se halla en la mitad sur de América del Norte.
El adulto mide de 2 a 3,4 cm. Son verde brillante metálico por arriba y negro el vientre y las patas. Están activos durante el día, con frecuencia a la sombra de árboles (en México recurren comúnmente a los mezquites y pirul (Schinus molle) para buscar un lugar para colocar sus huevos y esperar pareja. Al volar zumban de modo parecido al del abejorro debido a que no necesitan abrir los élitros. Las larvas crecen hasta 5 cm, son gruesas, blancas con la cabeza oscura, y tienen seis patas pequeñas e inútiles para caminar.
Las larvas suelen criarse en estiércol y alimentarse de este, principalmente de bovinos. Los adultos aparecen en junio. Se alimentan de frutos muy maduros o blandos (en Estados Unidos le llaman "escarabajo come higos"), pues no pueden morder materia dura. Más daño causan las larvas pues en algunas ocasiones penetran en el suelo y se alimentan de la raíz del pasto.
Girar con frecuencia las boñigas para que las larvas queden expuestas a los depredadores es el mejor método no químico de control de plagas.
Algunos niños atrapan mayates adultos y les atan un hilo entre los élitros o en una de sus patas (esto no se debe hacer, pues pueden terminar arrancando la pata), sujetando el otro extremo para que vuelen alrededor del niño como si fuera un avión de juguete, sin embargo, se debe tomar en cuenta que pronto hay que soltarlos y no hacerles daño.
