The elytra of this cockchafer beetle are readily distinguished from the transparent hindwings.. An elytron (/ ˈ ɛ l ɪ t r ɒ n /; from Ancient Greek ἔλυτρον (élutron) 'sheath, cover'; pl.: elytra, / ˈ ɛ l ɪ t r ə /) [1] [2] is a modified, hardened forewing of beetles (Coleoptera), though a few of the true bugs such as the family Schizopteridae are extremely similar; in true ...
Alaus oculatus can reach a length of about 25–45 millimetres (1.0–1.8 in). [2] They have an elongated body, black in color throughout. The pronotum exhibits a large oval patch of darker scales, framed in white, on each side - the common name of the beetle derives from this feature. The elytra are striated and mottled with silvery whitish ...
Adults have harmful effects for the crop when they aggregate in large groups. The larvae can cause severe damage and kill the plant by gnawing the plant roots. [5] The cockchafer develops via metamorphosis, in which the beetle undergoes stages of egg, larvae, pupae and adults. The mating behaviour is controlled by pheromones.
Elytra are typically a darker green, but can also have copper hues. Emerald ash borer is the only North American species of Agrilus with a bright red upper abdomen when viewed with the wings and elytra spread.
Among fruits, they have been found to damage apple and pear orchards. On apple trees specifically, Forficula auricularia feed on the fruits (primarily on parts where the fruit is already rotting or cracked) and contaminate the fruits with frass (powdery wood debris that is the result of insect foraging/ boring).

Adult Dermestidae are generally small beetles (1–12 mm long), rounded to oval in shape, with hairy or scaly elytra that may form distinctive and colourful patterns. [3] [4] Except in genera Dermestes and Trichelodes, there is a single ocellus in the middle of the head.
S. lacrymans is a form of brown rot, a group of fungi which digest the cellulose and hemicellulose in timber. This particular species poses the greatest threat to buildings since it can spread through non-nutrient providing materials (e.g., masonry and plaster) for several meters until it finds more timber to attack.
