| Yes, they're mealies. My experience with them has been that if you see one, there are a bunch more hiding, and probably some on other plants as well.
With that many, check the flowers carefully, including inside the lip and between petals for them. Also look closely at the place where the leaf attaches to the stem, and if you can, at undeveloped nodes on any spike.
These make wonderful hiding places and I have found mealies all those places, even when it looked like there were only one or two on the plant. Whenever they keep reappearing over a long period, be sure they have a secret hiding place you haven't found yet.
To get the ones lodged between leaf and stem I make sure to shoot enough insecticidal soap in there to seep down. The ones in the undeveloped spike nodes-- short of cutting open the nodes I don't know how to get those.
On flowers, wash them off with a drop of dishwashing liquid on a Q-tip. |
