It’s on a stem don’t spider mites lay eggs on leavesThat is an egg, I don't know what species. I know my insects really well but larvae and eggs were the next semester.
I dont think its an egg now i think it may be a scale bug. When i tryed to take it off it was kinda stuck there and looked like it was sucking the stem. Edit doesnt this scale bug look kinda like the bug on my plantMy entomology prof would say;
"If you want to know what's in the egg, hatch the egg."
Stick it in a glass and saran wrap the top. Hatch the egg because it looks like it's hatching anyways. Larvae are easier to id than eggs.
