brown spots from spider mites on Philodendron Micans
Quick answer
If your Philodendron Micans has brown spots from spider mites, the most likely cause is: Philodendron micans' velvety (pubescent) leaves are particularly susceptible to spider mite infestations that appear as brown or translucent stippling spots. The hairy leaf texture traps dust and provides ideal habitat for Tetranychus urticae mites. Unlike edema which causes water-soaked translucent spots or bacterial infection which creates angular lesions with halos, mite damage shows fine stippling pattern often with visible black dots (mite frass) and fine webbing on leaf undersides in advanced stages.
Start here:
- 1. Quarantine plant immediately to prevent spread to collection
- 2. Inspect leaf undersides with 10x loupe or phone macro lens for tiny motile specks and fine webbing
