What striking physical characteristic defines the appearance of adult Anoplognathus species?
Answer
Iridescent, metallic sheen (green, bronze, or gold)
The most memorable physical trait of the adult Christmas beetle is its brilliant coloration, described as an iridescent, metallic sheen. This shimmering appearance can manifest in colors such as bright green, bronze, or gold, making them visually appealing specimens despite their pest status. This dazzling exterior acts as a significant visual marker, often differentiating them easily from many neighboring insects that possess duller, brown, or black coloration. This sheen is a characteristic feature often associated with members of the Rutelinae subfamily.
