#Cicadas

Along the New Brighton coast and only since about 2016, we've also got the clapping cicada, *Amphipsalta cingulata*. When Thursday's Waitangi Day hikoi reached New Brighton Pier, I heard a distinctly different cicada calling. It's got a pulsing, ascending rattle. It has spread down into the South Island from the North Island this century, presumably in response to the warming climate.

In Banks Peninsula and the Port Hills, but not Christchurch city, there's the chirping cicada *Amphipsalta strepitans*. I informally call it the maraca cicada because it reminds me of someone shaking a maraca. I don't yet understand why this species is not in the city itself. It cuts out at around the edge of the housing in the Port Hills.

In Christchurch city and the Port hills and Banks Peninsula, we've got the Kihikihi Wawā or Chorus Cicada, *Amphipsalta zelandica*. Its calls sound like pulsing static. These are the cicadas that make a cacophany from the trees of the botanic gardens and Hagley Park. They are abundant and all of them singing together is *loud*.

Ōtautahi-Christchurch is finally starting to feel like summer, with the cicadas turning up the volume from the trees.

On Thursday I was reminded that we've now got three large, loud cicada species calling in the city. They all sound distinctly different when you get your ear in.

One is a recent arrival from the North Island and so far is only along the coast of the city.

I've put recordings of each in the following posts.

Meet Strawberry Claws—a new species of hermit crab phys.org/news/2024-11-strawber

A new species of #HermitCrab in the genus #Strigopagurus from the continental shelf off south-east #Queensland, #Australia museum.qld.gov.au/collections-

"the #NewSpecies has several highly distinctive features. Most striking is its bright red claws, but it also has evolved its own unique method of producing underwater sound (#stridulation), much like #cicadas do in the air."

Ancient #cicada wings evolved to deal with evolutionary changes in birds phys.org/news/2024-10-ancient-

"in their earlier years, #cicadas typically had wingspans similar to modern butterflies... But over the course of approximately 160 million years, the wings across all species began to grow a little wider even as they became slimmer... to fly up to 39% faster"

Painting gold embellishments onto a few limited edition Magicicada prints so they’re ready for next weekend’s art festival. These are pretty labor intensive so I’m only making a small number.

I currently have a couple listed in my shop, and I also have small prints available.
