Tibicen canicularis in Keene, NH

My neigbors spotted about 20 - 30 insects emerging from pupae low on the trunks of several white pine trees in their yard, across the street from our home. I found no cicadas emerging from the white pines on our yard. I did not measure the insects, but their bodies were at least one inch long, with wings extending beyond the tip of the abdomen. They were mostly sessile, with only weak movements of legs and wings. However, when we returned later in the afternoon, we found only empty puparia; the adults had disappeared from the tree trunks.

Hi Ken,

Sounds like you hit a peak emergence period in your neighborhood for these cicadas. They are known as Tibicen canicularis - the Northern Dog Day cicada.

They do have a tendency to emerge in greater numbers later in the summer. I have been spending a lot of time in New Hampshire as of late documenting species there. You will be happy to know that I have documented at least 5 different species of cicadas.

Thanks very much for sharing your photos and adding your sighting to our distribution database.
