Cicada Fun with Google Trends

Note: I originally took this article down because embedding Google Trends slowed down the loading of the page. I’m republishing without the embeds.

This article was inspired by Serious Fun with Google Trends by Simon Leather.

Google Trends is a Google website that lets you see trends in the search terms over time. When people search for “cicada” it usually means cicadas have emerged in their area at the time they search.

The following graph shows when people searched for “cicada” over the past 10 years in the United States. The largest spike, in May of 2004, coincided with the emergence of Brood X. See it on Google Trends.

Google Trends 2004-2015

You might think that periodical cicada emergences cause the largest spikes, but not always — and not just because periodical cicadas don’t emerge every year.

2004: Cicada searches spiked May 16-22, which was Brood X — Magicicadas.
2005: Jul 31-Aug 6 spike which was for Neotibicen Cicadas. No periodical cicadas.
2006: Aug 13-19, Neotibicen Cicadas. No periodical cicadas.
2007: May 20-26, Brood XIII — Magicicadas.
2008: Brood XIV Magicicadas emerged (spike Jun 8-14), but the largest spike was Jul 29-Aug 2, Neotibicen Cicadas.
2009: Aug 16-22, Neotibicen Cicadas.
2010: Aug 8-14, Neotibicen Cicadas.
2011: May 29-Jun 4, Brood XIX — Magicicadas.
2012: Jul 29-Aug 4, Neotibicen Cicadas.
2013: May 5-11, Brood II — Magicicadas.
2014: Brood XXII — Magicicadas had a relatively small spike May 25-31, compared with Aug 24-30 for Neotibicen Cicadas (late season due to cool weather). There was also a teeny bit of a spike around January of 2014 due to the “cicada 3301” meme/game.
2015: Brood XXIII & IV Magicicadas emerged (spike around Jun 7-13), but the largest spike was around Aug 9-15 for Neotibicen Cicadas.

Which cities had the most cicada searches over the past 14 years? Nashville, Baltimore, Cincinnati, Arlington, Washington, Alexandria, Pittsburg, St. Louis, Columbus, and Chicago. Time to move to Nashville.

Australia

In Australia, searches for “cicadas” peaks in December (summertime in Australia). It looks like there is a year-over-year pattern arising as well, with peaks every 4 years (2009, 2013, 2017) particularly, if you drill down to New South Wales.

Japan

In Japan, searches for “セミ” peaks in August.

Other countries

  • Argentina peaks in March for cigarra.
  • Brazil peaks in October and April for cigarra.
  • France peaks in July for cigales.
  • Mexico peaks in May or June for chicharra, but October for cigarra.
  • New Zealand peaks in February for cicadas.
  • South Korea peaks in July for 매미.
  • Spain peaks in July for cigarra.

Now I know when to visit these countries. 🙂

14 new species of grassland, woodland & scrubland Myopsalta cicadas

Lindsay Popple published a new paper describing 14 new species of grassland, woodland & scrubland Myopsalta cicadas. Download it from Zootaxa.

Here are the particulars:

Volume: Zootaxa 4340 (1): 001—098; 2017.
Title: A revision of the Myopsalta crucifera (Ashton) species group (Hemiptera: Cicadidae: Cicadettini) with 14 new species from mainland Australia
Author: LINDSAY W. POPPLE

Abstract:

The genus Myopsalta Moulds is distributed throughout much of Australia. Previous studies have associated several undescribed species with the Myopsalta crucifera (Ashton) species complex. The present study informally divides the cicadas in the genus Myopsalta into two species groups. It provides a revision of the M. crucifera species group, which includes redescriptions of M. crucifera s. str. and M. mackinlayi (Distant). The identity of the latter species is further refined and attributed to material formerly presented under the name Myopsalta atrata (Goding & Froggatt). In addition to the redescriptions, 14 new species belonging to the M. crucifera species group are described, including M. albiventris n. sp., M. bassiana n. sp., M. chrysopedia n. sp., M. gordoni n. sp., M. leona n. sp., M. longicauda n. sp., M. majurae n. sp., M. melanobasis n. sp., M. parvula n. sp., M. platyptera n. sp., M. riverina n. sp., M. septa n. sp., M. umbra n. sp. and M. xerograsidia n. sp. A key to species in the genus Myopsalta is provided. Standard morphological descriptions and descriptions of calling songs unique to each species are included along with a discussion on different song types in the M. crucifera species group.

New species of Clinopsalta cicadas

Lindsay Popple announced on Twitter that two new species of Clinopsalta cicadas have been described.

Sounds: Calling songs of Clinopsalta cicadas.

Journal Article: TWO NEW SPECIES OF CLINOPSALTA MOULDS (HEMIPTERA: CICADIDAE) AND ADDITIONAL DISTRIBUTION RECORDS FOR CLINOPSALTA ADELAIDA (ASHTON), WITH NOTES ON THEIR DISTINCTIVE CALLING SONGS. Popple and Emery, 2017. Rec. Aust. Mus. 69(4): 237—256

Abstract from the journal article:

Two new species are described in the genus Clinopsalta Moulds. Clinopsalta autumna sp. nov. exhibits a warm temperate distribution from south-east Queensland south to Goulburn and Nerriga in eastern New South Wales. Clinopsalta semilunata sp. nov. has a patchy distribution in southern Queensland from Binjour Plateau west to near Miles, south to Yelarbon State Forest and Durikai State Forest, both near Inglewood. In addition to the descriptions of these new species, further distribution records are provided for C. adelaida (Ashton), which extend its distribution from south-eastern South Australia and northern Victoria to inland central and northern New South Wales. The species of Clinopsalta are small—medium sized cicadas (< 20 mm body length) with distinctive calling songs of an intermediate frequency (c. 6 to 18 kHz). The temporal structures of the calling songs follow a similar pattern in each species, comprising an introductory rattle followed by a series of clicking phrases. The call is characteristically accompanied with bouts of prominent wing-snapping, except in one species (C. semilunata sp. nov.).

An early start to Australia’s cicada season

Cicada researcher and photographer Nathan Emery found his first Bladder Cicada (Cystosoma saundersii) for the year. See this iNaturalist page. It is still winter there, so this is particular interesting.

If you’re in the Sydney, Australia area and you see or hear a cicada this season, report it to the Great Cicada Blitz, an iNaturalist website set up by cicada researcher Nathan Emery. The purpose of this website is to map and identify the various cicada species in the Sydney area.
