Hey E.G. Thanks for quick reply. Not cold. The webbing is most definitely spider webs. I live in north qld but at elevation, so am technically in the tropics but weather is obviously more temperate. Point being my potting mix is more of a mineral mix than most people would use for Trichocereus.sp. Lets say even parts coarse sand, 5mm gravel, perlite, and potting mix. I wash the minerals and sift for fine particles and sift the potting mix for bark. I also water my plants very sparingly due to humidity. Maybe once a month in the growing season. The plant "feels" fine, not soft or squishy, etc. Will pull up plants in question and check for pests. Whats this bugs name?
