What does spider mite look like on houseplants in photos? - briefly

Spider mites show up in images as tiny yellow‑to‑reddish specks clustered on leaf surfaces, often creating a stippled or stippling pattern, with fine silvery webbing visible on the undersides of foliage. The webbing resembles a delicate, dusty coating that connects the minute insects.

What does spider mite look like on houseplants in photos? - in detail

Spider mites on indoor foliage appear as tiny, often invisible, specks that become evident under close‑up photography. Individual bodies measure 0.2–0.5 mm, resembling translucent, oval grains. Their coloration ranges from pale yellow to light green, sometimes taking on a reddish hue when fed heavily. Because the exoskeleton is thin, most photographs capture only a faint outline unless lighting is adjusted.

Key visual indicators include:

  • Webbing: Fine, silk‑like threads radiating from leaf edges or undersides. In macro images the webs form a delicate mesh that can be mistaken for dust.
  • Leaf stippling: Small, pale or bronze spots where mites have pierced cells. High‑resolution photos show a mottled pattern, often concentrated along veins.
  • Discoloration: Yellowing or bronzing of tissue surrounding feeding sites. Close‑up shots reveal a gradient from healthy green to the affected shade.
  • Mite clusters: Groups of 5–10 mites may be visible as a cluster of tiny dots on the lower leaf surface. Proper focus and a macro lens display them as a faint, stippled line.
  • Damage patterns: Irregularly shaped, semi‑transparent patches where the chlorophyll has been depleted. When photographed with a flash, these areas appear as lighter, almost translucent windows in the leaf.

When photographing for identification, optimal conditions are:

  1. Use a macro lens or a smartphone with a macro attachment.
  2. Illuminate the leaf from an angle to cast shadows that accentuate the webbing.
  3. Capture both the upper and lower leaf surfaces; mites preferentially reside on the underside.
  4. Employ a high ISO setting to reveal the faint bodies without introducing excessive noise.

By focusing on these characteristics—minute, translucent bodies, delicate silk threads, stippled feeding marks, and localized discoloration—photographs can reliably convey the presence and severity of spider mite infestations on houseplants.
