I'm new to this forum but not to growing carnivorous plants. This year due to quarantine I finally became motivated/acquired enough time to organize my collection and I'm realizing that my flytraps are collecting maybe dust/mold in their traps.
The white dots I know were aphids but they are usually only a problem in spring while during summer they diminish.
I keep the plants under a 30% shade cloth during summer when temps reach over 85F, they get plenty of air circulation and water but they are right above a street where a ton of cars pass by and throw dust around. So anyone know what may be causing this? I dont think its too harmful as I think they've had this on them for a while now but it goes away in winter and comes back in the summer only.
