Adults are 5-7.9 mm long, long and narrow like mosquitoes, with reddish-brown to orange tentacles, metallic chest and feet, nose, compound eyes with slightly protruding hemispheres and black eyes. The end of the antenna is long, and the female insect is oval, which is slightly shorter than the sum of the other nine sections. The end of the male insect is rod-shaped, which is longer than the sum of the other nine nodes. The front chest is long and narrow, and the back end of the front chest retracts into the middle chest like a neck at 1/3. COLEOPTERA's overlapping wings are oblong, wider than the front chest, with 22 inconspicuous longitudinal points on the surface, and the rear wings are wide and thin. The feet are slender and the legs are nearly rod-shaped. Eggs are milky white to yellowish white, oval, with thin shells and small pits on the surface. (Sweet Potato Ant Elephant-Baidu Encyclopedia)
