We found a Scrub Plum (prunus geniculata) being visited by a Hairy Maggot Blow Fly (chrysomya rufifacies) who, apparently, fuels on plum-flower nectar between carrion feasts. The hairs on the fly’s face, or even its proboscis, may pollinate the Scrub Plum’s beautiful flowers.

While it is probable that this Blow Fly will pollinate the Scrub Plum, it is unlikely the same would cross-pollinate Jujube (pseudoziziphus parryi), due to its limited range and lifespan. This is why Johnny believes a wider-ranged butterfly, possibly with brush feet, is more likely to be required for cross-pollination of Ziziphus in Florida.
Found in the Lake Wales Ridge State Forest area blooming in early February, 2021.
