The leaves are green, but a hairy-like substance is hanging about 2 inches on the underside of the hibiscus. Currently, it is affecting a small cluster of leaves (about 12 leaves). Otherwise the plant is healthy and blooming. The affected area is in shade and down low on the plant. Any ideas? enter image description here

  • Never seen anything like that before - have you poked around inside the white fibres or looked with a magnifying glass to see if there is an inhabitant or two, such as small caterpillars? Anything odd under the leaves, where the fibres are coming from? – Bamboo Jun 12 at 17:40

    We cut off those branches, and white flies are flying around the area. In researching, we suspect they're called giant white flies. We're hosing down the area as recommended. Weirdest thing we've ever seen – Bev A Jun 13 at 15:06
  • Fascinating, never heard of giant whitefly, never mind seen such a thing as these dangly filaments, but I looked it up and I think you're right - image here is very similar whatsthatbug.com/2010/06/14/giant-whitefly. Thanks for letting me know! – Bamboo Jun 13 at 17:00
