Gene Kritsky wrote us to let us know that Brood III periodical cicadas are emerging in Iowa and Missouri.
I wanted to let you know that I have received emails with reports of
emerging periodical cicadas in Iowa and northern Missouri in Brood III
territory. These cicadas would be emerging four years early similar to
the early emergences observed in 2000, 2003, 2004, and 2009.
Tribe (Psaltodini) information comes from: MARSHALL, DAVID C. et al.A molecular phylogeny of the cicadas (Hemiptera: Cicadidae) with a review of tribe and subfamily classification.Zootaxa, [S.l.], v. 4424, n. 1, p. 1—64, may 2018.

David Emery send us a photo of a Cystosoma saundersii (bladder cicada) from Australia and we added it to the gallery.
Just to complement the Aussie cicadas, a small colony of these Cystosoma saundersii have been droning and rattling at dusk around Burwoood in Sydney for the past 2 months. This is their southern-most extension down the east coast of Australia.

This is a photo of the amazing Bagpipe cicada (Lembeja paradoxa) was taken by Timothy Emery (David Emery’s son).
Attached is a photo taken by my son, Timothy Emery from Thursday Island, Torres Strait off Cape York, Queensland. This a male “bagpipe cicada” (Lembeja paradoxa) singing for his female. These guys at rest look like dead leaves with wings folded under stems of grass, but when singing at dusk, rush up the stems and can expand their abdomens incredibly up to 5-10 x resting size (hence the bagpipe bit) and emit a very loud droning sound for their size. A great emergence of these on Thursday Island in the first 2 weeks of January.
The Bagpipe cicada can be found in the Northern tip of Queensland, from October to February, but they’re most common during January. (Moulds, M.S.. Australian Cicadas Kennsignton: New South Wales Press, 1990, p. 178)
David Marshall and Kathy Hill have discovered that a particular species of katydid mimics the wing-flick of female cicadas to lure male cicadas to their certain doom.
We have found that predatory Chlorobalius leucoviridis katydids (Orthoptera: Tettigoniidae) can attract male cicadas (Hemiptera: Cicadidae) by imitating the species-specific wing-flick replies of sexually receptive female cicadas. This aggressive mimicry is accomplished both acoustically, with tegminal clicks, and visually, with synchronized body jerks. Remarkably, the katydids respond effectively to a variety of complex, species-specific Cicadettini songs, including songs of many cicada species that the predator has never encountered.
Roy Troutman sent me these photos of temperature loggers that allow cicada experts, like Gene Kritsky, to measure the ground soil temperature, and improve their formulas for predicting Magicicada emergences.
We [Gene Kristsky and Roy Troutman] buried 3 temperature probes & tied one on a tree branch for air readings. The temperature loggers will take a very accurate reading every 10 minutes & after the emergence has started in full swing Gene will dig them up & hook them to a usb cable & download all the data to his laptop for study. He [Gene] is trying to determine the exact temperature that they will emerge so he can fine tune his formula for calculating emergence times.
Last year Gene’s emergence formula calculator (try it!) did a good job of predicting the Brood XIII emergence, and the 2008 temperature study should only improve it.
You might be able to participate in the 2008 cicada temperature study. If you’re interested, contact Gene Kritsky.
Here’s yet another wonderful cicada photo from David Emery in Australia: the Diemeniana euronotiana. The cicada is a mere 20mm in length, and they are now just out in the bushland around 1000m.
The Diemeniana euronotiana can be found in eastern NSW, south-eastern Victoria and Tasmania. They are most common in late November to January. (Moulds, M.S.. Australian Cicadas Kennsignton: New South Wales Press, 1990, p. 112)
