Muellerina eucalyptoides is a widespread species in Queensland, New South Wales, Victoria and South Australia which has mainly Angophora and Eucalyptus as hosts.

Is anything known about the pollinators of this mistletoe?

It seems that they are likely to be bird pollinated to the quote Watson, p 124 "Australian mistletoes display the suite of floral characteristics that typify bird-pollinated plants". We do have honeyeaters locally which are said to be the main pollinators - Eastern Spinebills, New Holland Honeyeaters and Red Wattlebirds. "Their long bills are considered to be ideally suited to extracting nectar from these narrow flowers."

Before I started UV photography I thought that all mistletoes were the same - how wrong I was, I have now found four different species in our own garden within perhaps 100 m of each other! Another Trivial Pursuit fact for you - Tasmania does not have mistletoes. Since this is the time of year for mistletoe flowers I will post new examples of the other three to include UVIVFL.

Another quote "Australia is home to 91 species of mistletoe from three of the four families in which aerial hemiparasitism evolved independently" "Despite popular opinion, mistletoes are not introduced plants - every mistletoe plant growing in Australia is a native plant".
