Hi, I saw this on my monstera adansonii and immediately freaked out and sprayed a neem oil mix like crazy and took a paper towel to wipe up that spot. I didn’t see anything on the other leaves or elsewhere. I’ve been overall incredibly lucky with pests and never had an issue with this particular plant. Do you know what this pest is / how I should treat it (if it needs more than neem oil)? Thank you so much!!!
