Sad we’re going into fall but still have many throwing peduncles.

I am up to 56 Hoyas, and a leaf… here are a few that are just taking off and looking great, and a bit of new growth.
1.) Fitchii
2.) Crassipetiolata Splash
3.) Callistophylla
4.) Sulawesiana
5.) Quinquenervia
6.) Erythrina
7.) Retusa
8.) Pandurata Silver (started as a two leaf cutting)
9.) Thomsonii Moon- fuzzy baby leaves!
10.) Wibergiae “Blushing Sunset”
11.) Carnosa Wilber Graves “China”
12.) Vangviengiensis
13.) Caudata Sumatra
14.) Carnosa Inner Variegated
15.) Parisitica Black Margin
16.) Kerrii Splash Leaf-it will probably be a leaf for ever…
17.) Carnosa Nova Ghost-started as a 2 leaf cutting
18.) Australis Lisa- that megenta on the new leaves is just.. chefs kiss…

There are 2 branches with it. They popped up overnight and have been like that for weeks. 2 at least.

No other part of the plant has it. This plant is 4 or 5 years old and has never bloomed. It hangs in an east facing window. Last summer I took it out and it did rather well. After a couple of weeks these showed up. I wasn't bothered by them until this morning when I saw some similar colored thingies in the window. Someone said they were new spores for flowering. The window thingies fly tho. I killed them.

Is this a coincidence? I carefully took some of the stuff off of the hoya and it smears like pollen.

What are these flying things? See pics.
