Clay-Coloured Weevil

The Clay-coloured Weevil, Otiorhynchus singularis, is a small flightless beetle in the family Curculionidae native to Europe and widely established as an introduced pest in many parts of North America and other temperate regions. The adult weevil is typically 5–7 mm in length, mottled gray-brown or clay-colored with patches of pale scales that provide camouflage against bark and soil. Like other Otiorhynchus weevils, the Clay-coloured Weevil is parthenogenetic in most introduced populations, consisting entirely of females that reproduce without mating. Adults are nocturnal, feeding on the foliage and bark of a wide range of host plants including strawberries, raspberries, currants, ornamental shrubs, and nursery stock. The larvae develop in soil, feeding on roots and causing significant damage that can girdle and kill established plants. The species is considered a serious horticultural pest in affected regions, causing economic losses in soft fruit production, nurseries, and ornamental plantings. Management typically involves biological control using entomopathogenic nematodes or fungi, as chemical control of soil-dwelling larvae is difficult. The species is well established across temperate Europe and has been accidentally introduced to parts of North America through the horticultural trade.

Green Sea Turtle

The green sea turtle is one of the largest sea turtles. They are named for the green color of their cartilage and fat, not their shells.
