What is the typical length range, in millimetres, for adult Christmas beetles?
Answer
20 to 30 millimetres
Adult Christmas beetles are substantially sized insects, generally noticeable due to their length, which ranges between 20 and 30 millimetres. This size contributes to their high visibility when they emerge during the summer months. This dimension helps distinguish the flying adults from smaller ground beetles found in similar habitats. Their size, combined with their striking coloration, ensures they capture attention, even though their lifespan as adults is relatively brief, focusing mainly on reproduction.
