Cicada Fungi Research

Many types of fungi will eat cicadas, but one type — the Massospora — specifically infests and destroys cicada genitalia. Specifically, Massospora cicadina attacks Magicicada cicadas, and Massospora levispora attacks Okanagana rimosa. According to the website MycoBank Database, there’s at least 19 species of Massospora. By the names of some, you can guess which cicada it infects; Massospora diceroproctae likely infects Diceroprocta cicadas.

It’s not certain, but there are sure to be many more species of Massospora fungi — if not one for each species, perhaps approximately one for each genus. Considering that Massospora infects cicadas all around the world, it’s fair to assume that Massospora have been infecting cicadas for many millions of years.

At West Virginia University, Matt Kasson & his team are studying Massospora, and are looking for samples of cicadas with these infections. Matt regularly Tweets photos and finding such as this one of spores from a Platypedia cicada:

You you have some samples of such cicadas, and are willing to part with them, let Matt know.

What eats cicadas?

Filed under: FAQs,Massospora cicadina — Dan @ 1:32 pm

What eats cicadas? A better question is: what doesn’t eat cicadas?

Pretty much every creature with a mouth will eat a cicada, given the chance. Even organisms without mouths like fungi will consume cicadas.

People, pets, rodents, marsupials, reptiles, birds, fish, insects, arachnids — virtually any creature will eat them.

Some insects are known for specifically preying on cicadas, for example, Cicada Killer Wasps are well known for capturing cicadas for their larvae to eat them.

What eats them when they’re underground? When they’re underground they’re often eaten by moles and other furry insectivores, but enough of them escape the moles for the species to survive.

Read are cicadas safe to eat if you’re planning a cicada buffet.

Which fungus attacks Magicicadas? Massospora cicadina

Filed under: FAQs,Magicicada,Massospora cicadina — Dan @ 8:32 pm

The fungus Massospora cicadina preys on Magicicadas cicadas. This is particularly interesting because the fungus is able to prey upon them in spite of their long 17 year life cycle (apparently fungi are not phased by prime numbers).

When the fungus destroys the abdomen of male cicadas, they will behave like female cicadas and flick their wings in response to the songs of male cicadas, and attempt to mate with other males.
