About Orthorhinus cylindrirostris (J.C.Fabricius, 1775)
Description: Color and adult body size of Orthorhinus cylindrirostris are extremely variable; adult body length ranges between 10 and 20 mm. This species typically has one tubercle on each side of the pronotum. Each elytron has two tubercles located on the 2nd interstices, and a similar tubercle is present on the posterior declivity of the 5th interstice. Males can be distinguished from females by several traits: male antennae are positioned much closer to the apex of the rostrum, males have longer forelegs than females, and the three basal tarsal segments are more expanded in males than in females. Females are shorter, less cylindrical, and have a coarser body texture than males. Life cycle: Both adult weevils and larvae of Orthorhinus cylindrirostris feed on various Eucalyptus species.
