ANTENNA: Thread-like

SIZE: 25 - 30 mm in length

HABITAT: Adults are found in foliage of palm trees where they lay eggs at the base of tender leaves. Larvae consume palm leaves and tree tissue, thereby killing the palm trees

Mites and Ticks are Acari found across the polar regions to sulphur springs; from deep mines to fresh water and even in seawater. Practically, no biome is Acari-free. After bacteria, they are the most successful organisms on the planet. They have adapted for both free-living as well as parasitic lives. Mites have given up their predatorial quest and tend to be plant-feeders or scavengers while Ticks are predators and bloodsuckers.

ORDER ACARI(Mites and Ticks)
