Beetles on new Namibian stamps

Beetles on new Namibian stamps

Nampost issued a set of 5 stamps illustrating beetles of Namibia. The stamps created by the Namibian designer Helge Denker feature Red-Spotted Lily Weevil, Garden Fruit Chafer, Lunate Ladybird, Glittering Jewel Beetle and Two-spotted  Ground Beetle.

Red-Spotted Lily Weevil (Brachycerus ornatus) reaches a length of about 25–45 millimetres (0.98–1.8 in). Its body is black, with red spots and markings, the abdomen is quite rounded and the pronotum is strongly ridged, with round tubercles. Adult beetles feed on foliage of lily and females lay eggs in burrows close to the bulbs, while larvae feed on the bulbs and pupate in the soil.

Garden Fruit Chafer (Pachnoda sinuata) is part of the large family Scarabaeidae, which also include the scarabs and dung beetles. This species is large with a smooth carapace. Colouration is variable but basically yellow with dark brown central area broken by yellow spots and a transverse yellow line across the rear of the elytra.

Lunate Ladybird (Cheilomenes lunata) is a species of the Coccinellidae family. Coccinellids are mostly predators that feed on aphids and scale insects. A few are herbivores and can be detrimental to certain crops. Coccinellids are small, ranging from 1 mm to 10 mm (0.04 to 0.4 inches), and are commonly yellow, orange, or scarlet with small black spots on their wing covers, with black legs, head and antennae. Such colour patterns vary greatly however.

Acmaeodera viridaenea (Glittering jewel beetle) is a torpedo-shaped, hard-bodied beetle that vary considerably in size (2-50mm) and colour. They are brightly coloured with metallic colours. Beetles are heat-loving and can tolerate very high temperatures so are active in hot, sunny conditions when they are very alert, making them difficult to catch. The adults feed on pollen, foliage and nectar. The females lay their eggs in bark crevices and the larvae tunnel into wood and plant stems

Two-spotted Ground Beetle (Anthiini Carabidae) is largely restricted to Africa and is especially diverse and abundant in the arid, sandy Karoo and Kalahari regions of southern Africa. These are large, powerful predators that rely on speed and agility for capturing prey. The beetles employ chemical defense in the form of secretions from a pygidial gland located in the area of the ninth abdominal segment. The chemical cocktail within these secretions contains concentrated organic acids or quinone that can be squirted at potential predators in a strong jet.
