Silver beetle bottomside
Hydrophilus piceus
Great Silver Beetle (female)

The under side of this female Great silver beetle shows how the species got it's name. The air supply kept on the belly (called a plastron), reflects the light like silver. The air is kept there by means of a layer of special hairs. On the head the antenna are visible: they are folded back against the neck, parts of the clubs are just visible, the rest is hidden in the silver of the airbuble. The longer, projected "antenna" are the palps of the jaws.
