dog day cicadas (_Neotibicen canicularis_) I've seen recently
Automatic recognition of insect sound could help us understand changing biodiversity trends around the world -- but insect sounds are challenging to recognize even for deep learning. We present a new dataset comprised of 26399 audio files, from 459 species of Orthoptera and Cicadidae. It is the first large-scale dataset of insect sound that is easily applicable for developing novel deep-learning methods. Its recordings were made with a variety of audio recorders using varying sample rates to capture the extremely broad range of frequencies that insects produce. We benchmark performance with two state-of-the-art deep learning classifiers, demonstrating good performance but also significant room for improvement in acoustic insect classification. This dataset can serve as a realistic test case for implementing insect monitoring workflows, and as a challenging basis for the development of audio representation methods that can handle highly variable frequencies and/or sample rates.
It's still dog day cicada (_Neotibicen canicularis_) season around here. Spotted last night.

Stayed out late to look for the first dog day cicadas (_Neotibicen canicularis_) and I found them! A nymph climbing up a tree, still looking for a place to molt; and a freshly molted adult clinging to its exuvia.

#InsectSaturday: the sound of summer. An adult dog day cicada, _Neotibicen canicularis_, found in Trinity Bellwoods. Don't worry, I put it back.

But not every cicada emerges successfully. My first find was this partially emerged cicada being rapaciously devoured by the big carpenter ants (_Camponotus_) that also live in the willows. They were carrying away great hunks of meat in their jaws. Seeing this, I was surprised that any cicadas managed to molt successfully at all!

Went cicada-ing among the big willows down by the lake last night and was gloriously rewarded!
These are dog day cicadas, _Neotibicen canicularis_.
