cicada cast-off skin

Sitting outside this afternoon, I tried guessing at the temperature by listening to some crickets. I do know that crickets chirp faster as temperatures rise, and slower when temperatures fall. I’m sure my parent’s were unaware of Dolbear’s Law when they told me about crickets and temperature (Temperature = 50+[(N-40)/4] where N = the number of chirps per minute), and math is not one of my strengths, but I could tell it was getting hotter.

If you can’t distinguish a cricket “song” from a cicada or a katydid, listen to a field cricket sound.

As an amateur phenologist (one who studies the seasonal changes in plants and animals), I’m interested in these sounds. Not that I could ignore the cicadas who are very noisily chirping around my house this month.

The cicadas are pretty creepy looking and their cast-off skins that they leave attached around the backyard are also creepy. Katydids are much nicer looking in their bright green. It is difficult to find them, but easy to hear their eponymous “Katy did! Katy did!” call from he trees. Can you hear females answering “Katy didn’t, didn’t, didn’t?”    Take a listen to them

katydid

They hide with their veined oval-shaped wings that look like leaves in the treetops. They start singing in August, but, if you can identify when they start their summer song, weather lore says that autumn will arrive 90 days later. I’m not sure I caught the first katydid, but today was the first day I noticed them calling. That makes autumn in Paradelle arriving November 16.

The katydids are singing for love, lust and a mate. It is mating season (August through mid-October). Feel the love?
