Ornate Checkered Beetle

Fascinating facts about the Ornate Checkered Beetle

• The ornate checkered beetle is restricted to North America and has never been recorded on any other continent. It is a member of the checkered beetle family Cleridae and sits within the subfamily Clerinae, placing it among a distinct group of predatory beetles. Its scientific designation is Trichodes ornatus, the name used by entomologists worldwide. This narrow distribution highlights its endemic status on the continent.
• The larvae of the ornate checkered beetle develop inside the nests of bees, primarily those belonging to the Megachilidae family. Within these nests they act as parasites, using the bee's resources for their own growth. This parasitic habit means the beetle larvae exploit the bee's nest as a protected environment for development, gaining shelter and food until they mature. Their presence is therefore tightly linked to the availability of suitable bee hosts.
• While residing in the bee nest, the beetle larvae feed on the bees' own larvae or on the pollen stored there. This diet supplies the necessary nourishment for the larvae during their growth phase. By consuming either the bee offspring or the pollen provisions, the larvae secure the energy required to reach adulthood. Their feeding strategy directly ties their early life to the resources accumulated by the host bee.
• When the beetle leaves the bee nest it abandons the parasitic diet of its larval stage and begins to feed on flowers. It shows a strong preference for yellow-coloured blossoms such as yarrow and milkweed, which provide the nectar and pollen it needs as an adult. This plant-based feeding replaces the earlier habit of consuming bee larvae or stored pollen inside the nest. The reliance on yellow flowers is a characteristic trait of mature ornate checkered beetles.
• Males measure between 5 and 11 mm, while females are larger at 7 to 15 mm in length.
