At the start of 2018 Australia has been having an awesome cicada season, which should continue through to March, depending on the species and part of the country.
The best months of the cicada season in New Zealand are December – April.
Throughout the world, annual cicada emergences will follow their usual cycles.
Periodical Cicada Emergences
The World Cup Cicada, Chremistica ribhoi, will return after 4 years in Meghalaya, India.
Magicicada cicadas will return in 2018 in New York State after 17 years. Brood VII aka the Onondaga Brood can be found in the Finger Lakes area of New York.
Magicicada stragglers should also make an appearance in limited numbers.
- Brood XXII stragglers, emerging 4 years late, in mid-east Louisiana, south-west Mississippi, south-west Ohio and north-central Kentucky.
- Brood VIII stragglers, emerging 1 year early, in western Pennsylvania, eastern Ohio, and the West Virginia pan handle.

20,000 or so years ago the earth was a colder place. Glaciers covered much of North America, including many states that currently are home to Magicicada, and other species of cicadas. There were glaciers in Wisconsin as recently as 9,500 years ago. The area below the glaciers were dominated by taiga, a landscape dominated by sappy evergreens and grasses (mastodon food). Florida was three times the size it was today.

What I’m curious about is this:
- Where were the Magicicada 20-10 thousand years ago? Did they exist in a primordial form some place in the primordial woodlands of mega-Florida?
- How did deciduous trees (oak, maple, ask, etc) spread northward, and how did the Magicicada spread with them?
- Did the spread of deciduous trees northward into America play a part in the unusual life cycle of Magicicada, including the long lifecycle and 4 year accelerations?
- Were the Neotibicen and Neocicada also living in mega-Florida or perhaps Mexico, and then spread northward as temperatures rose?
- Were Okanagana able to exist in the colder, evergreen-dominated taiga of the time of the last glaciers?
For some reason this stuff intrigues me. Thank goodness my local library has a Jstor account.
I felt bad about always using an illustration of North American cicadas, so I made a Green Grocer cicada for Australian fans.
Get this image on a shirt, mug or even a pillow case via CafePress (the mugs are the most affordable).
Here’s something for Windows users: cicada cursors.
If you like to customize your PC, you can swap out your cursor with a cursor shaped like a cicada.
Download the cicada cursor it today (download and unzip).
Here’s a tutorial for changing your cursor.
I have no idea if you can change the cursor on a Mac or mobile device.
Update! Try the new Magicicada cursor (.cur file in .zip file)!

Between now and the spring, I have to spend some time labeling the unlabeled species of cicadas on my site.
