After observation, two insect individuals were observed and classified as male on 28th of April 2020: and a female on the 1stof May 2020. Morphological characters (front, antenna, elytra, and legs) were described under a dissecting stereoscopic microscope with a 10x lens. Photographic pictures were also taken with a mobile camera without zoom. The individuals were identified as the long- horned beetle, Xylotrechus stebbingiwith the aid of the key created by (Gahan, 1906). Xylotrechus stebbingi length average as 2.2 cm in male and 1.9 cm in female. Corresponding figures for width is 0.6- 0.5cm. Head of hypognathous position front covered with minute hairs with a V-shaped red-brown protrusion, compound eyes look like commas or curved water droplet, antenna filiform of 10 segments. Pronotum has three black spots in an inverted triangle, looks like a rabbit face, pronotal base part has 2 white spots distributed above the scutellum. The elytra have three transverse white lines; the base and the tip have more fuzz. Pro-femurs reach the first transverse elytra line, pro-leg of the same length as meta-femur, the last one passes the body and elytra, meta-leg is as tall as the body approximately, meso-femurs reach the third transverse line. | ||||
