bed bug in this photo was caught in the act of
feeding, the pinkish surface in the background is
human skin. This individual is about 1/4" in length,
notice the reddish-brown coloration, absence of
wings, six legs, two antennae, prominent eyes, and
segmented (striped) abdomen.
"beak" can be seen arising from between the eyes and
extending to the skin surface (beside the thin, dark
hair). The beak is a hollow tube that holds the
mouth-parts which pierce the skin and allow the bed
bug to draw blood from its host.
