Parasitoid Wasp cocoon or eggs?
There are some white and orangish stuff, larvae?

Appreciate advice, thanks.

Thanks Sloan Tomlinson
No, they're some sorts of members of Coccoidea (scales and mealybugs) some of whom make cocoon-like structures around themselves as they feed. The photo labeled "adult wasp" doesn't really look like a wasp but some sort of fly, likely there to lick up honeydew

"This must be what Takagi is talking about in his recent article.

"In the forms referred to Rutherfordia, it is observable usually, and especially when
dry material is available in good condition, that male tests crowd together around female tests, forming a thick mass of wax. Whenever male tests occur separately from each other, it is clearly visible that they stand on the cephalic end, keeping themselves erect or suberect (somewhat oblique with the ventral side faced below) against the surface of the plant body on which they occur."
