What do plant bedbugs look like? - briefly

Plant bedbugs are tiny, oval insects measuring 2–5 mm, colored light brown to reddish‑brown, with a soft, flattened body. They have short, hair‑like hemelytra covering the abdomen and a piercing‑sucking mouthpart.

What do plant bedbugs look like? - in detail

Plant‑associated bedbugs are small, dorsoventrally flattened insects typically measuring 4–5 mm in length. The body is oval and tapers slightly toward the posterior. Adults exhibit a uniform reddish‑brown to dark brown coloration; some individuals show a lighter, amber hue on the abdomen.

The exoskeleton is smooth, lacking conspicuous setae. The head is short, bearing a pair of beaded antennae each composed of four segments, the basal segments being thicker than the distal ones. Compound eyes are prominent and positioned laterally on the head, providing a wide field of vision.

Mouthparts form a piercing‑sucking proboscis (stylet) adapted for extracting plant sap. The pronotum covers the thorax and is slightly wider than the head, with a smooth margin and no distinct ridges. Legs are slender, each ending in five‑segmented tarsi equipped with tiny claws that facilitate clinging to foliage.

The abdomen consists of five visible dorsal segments (tergites) separated by shallow sutures. Ventral surfaces display a faintly lighter coloration. Wings are absent in the adult stage; the species relies on walking and occasional passive dispersal via wind or human transport.

Key visual markers:

  • Size: 4–5 mm, oval shape
  • Color: uniform reddish‑brown to dark brown, occasional amber abdomen
  • Head: short, four‑segmented antennae, lateral compound eyes
  • Mouthparts: elongated piercing‑sucking stylet
  • Pronotum: smooth, slightly broader than head
  • Legs: slender, five‑tarsal segments, tiny claws
  • Abdomen: five dorsal tergites, smooth ventral surface
  • Wings: absent

These characteristics enable reliable identification of plant‑dwelling bedbugs in field surveys and laboratory examinations.
