This site discusses in detail the artificial fertilization of Hoyas. This is absolutely the most specific information on Hoya fertilization and breeding I have ever seen.

This Wiki site on Hoya australis lists the pollinator under Ecology. In this case the pollinator the Southern Grass dart which is a small butterfly very much like our own skipper butterfly species.

This very interesting study explains that New World plants that belong to the Asclepidaceae are predominantly pollinated by butterflies where as Old World Asclepidaceae, which includes all Hoya species, are pollinated almost exclusively by moths. The order Hymenoptera which includes the ants, bees and wasps are responsible for most of the other pollination that occurs in the subtribe of Asclepidaceae that includes Hoyas. Page 7 shows the graph that breaks down the pollinators by the insect orders. I knew learning some of those insect orders because of my beetle collection would come in handy one day. lol
If you are interested in knowing the insect orders to help decipher the graph do a search for Insect Orders.
This is a great study and full of info although it is not necessarily broken down into Hoya specific info. Eliminating the other members of Old World Asclepiads is quite easy though because many use the scent of carrion to attract flies vs the sweet smell of most Hoya flowers. Interestingly a small number of Asclepiads are pollinated by beetles (Coleopetra) and true bugs (Hemiptera), this may explain those less than nice smelling Hoyas.

The portion of Paul Shirley's Blog where he is discussing Hoya davidcummingii explains that most moth pollinated Hoya flowers have a large amount of white while the species in question (davidcummingii) has not been seen to be pollinated by moths.

This less useful for our purposes but still very interesting study discusses Hoya spartioides movement away from it's closest relatives which all offer liquid nectar to attract pollinators and towards a solid pollinator reward in an attempt to conserve water in a dryer environment.

Hopefully I didn't just put everyone to sleep?

Our second house came out very nice as we knew what to include. Grad school changed the plans on staying in that house. Have you ever met a rich grad student? :) Thank god that's over.

Our current build is very similar to our first house with all the mistakes corrected.

We have learned to despise the upkeep of wood/PT lumber. I'm very picky about not having wear marks too my front door. This house will have granite steps front & rear. No deck, but a patio.

Upstairs laundry. I workout 6 days/week training for triathlons, cross country so it generates a lot of laundry. Our current build will have a second floor laundry and there should never be a reason to carry a clothes basket up and down stairs.

More outlets than I could ever need. Cable TV outlet in kitchen for an under cabinet TV for my wife. Extra water spigot.

Sconces in the entry hallway for a more distinctive look.

More powerful bathroom fans.

Framed and finished hallway corners. Other than in the bedrooms, there are no corners in the house that are just drywall & mud.

Taller baseboard trim.

Gas fireplace. Soooo much cheaper to add when house is new.

Quality flooring. First house had contractor grade stuff that was total crap.

Upgraded furnance. Current build is near top of the line with several energy efficient add-ons. Cold start boiler with indirect tank and outdoor return.

Grilles in the windows. Out first house had the snap in kind. They were Andersen but the snap in grilles just sucked.

Current build will have flood lights to illuminate all four sides of the house. First house was front and back and the sides were like the dark side of the moon.

Master bathroom. First house was two full baths but no Mbath. This is something we'd never buy a house without again.

I could go on for an hour about how we hosed up our first build.......
