It was probably a Fiesta-ish piñata--maybe a colorful unicorn, donkey, or pony, right?
Bet it wasn't a fly.
An Acrocera fly proved to be a big hit last Friday night at the pre-Halloween gall-a at the Bohart Museum of Entomology, University of California, Davis.
Open to Bohart Museum associates and members of the Bohart Museum Society, the event drew dozens of costumed characters, from honey bees to black widows to a tarantula hawk.
But it was the anatomically correct fly, masquerading as a piñata, that grabbed the most attention. It was the work of UC Davis entomology PhD student Charlotte Herbert; her fiancé, George Alberts; and the Bohart crew.
It was all in keeping with UC Davis alumna Nicole Tam's creative drawing on the party invitation that featured an Acrocera fly, a larva, and a spider. Mama Fly is telling her little one, "You look wonderful, my little larva!" and the little one, in close association with a spider (her food), is responding with: "Thanks, Mom!
You could almost feel the love. Or the larva.
Entomology PhD student Jessica Gillung calls the Acroceridae family "a remarkable group of endoparasitoids of spiders." She knows the family well; it's the subject of her thesis dissertation. She studies "the evolution and systematics of Acroceridae, focusing on understanding host usage patterns and trends in morphological variation."
"The piñata depicts a species of the genus Acrocera, one of the most species rich genus in North America," Jessica explained. "These rare and elusive flies lay the eggs on the ground or vegetation, and the little larva is in charge of finding itself a suitable host. Upon finding the host, the larva enters its body and feeds inside until it's mature to come outside and pupate. They eat everything from the spider; nothing is wasted."
Charlotte, who studies Asiloidea phylogenetics with a focus on Asilidae (aka assassin flies) and their predatory lifestyle and venom, came dressed as Maggie the Maggot or an Acroceridae larva, about to pupate and turn into a fly. She added a spider corpse to her costume "as my meal in honor of the party invitation made by Nicole Tam."
Charlotte's fiance, George, came as "Farmer Maggot," or his interpretation of Farmer Maggot from "The Lord of the Rings."
And Jessica? What did she portray at the Halloween party?
A spider? No. A fly? No. Herself? No.
A Procyon lotor. A raccoon.
