Sound Ideas: Three Meadow Katydids

by Carl Strang

Today I am sharing recordings of 3 species of large meadow katydids (genus Orchelimum). One way or another their songs all fit the ticks-and-buzz pattern characteristic of their group. I will order them idiosyncratically, by how well I can hear them in the field. I will be interested in any comments on how well you can hear them in these recordings. The first is our most common species in the genus, the black-legged meadow katydid O. nigripes.

This was a very warm individual who was rushing the ticks. I render the pattern tickety-buzz, as there usually are 3 ticks leading directly into the buzz, with a brief pause before the next set. This species usually can be found in or near wetlands. I can hear its song unaided without any trouble.

Next up is the long-spurred meadow katydid, O. silvaticum.

Here the ticks have much the same quality as the buzz, several very brief rattles that merge into the rattling buzz. This is a katydid of woods edges and adjacent areas with tall herbaceous vegetation. I can hear some of these unaided in the field, on a calm day without other competing sounds, or when there are plenty of reflecting surfaces, but usually I need the SongFinder pitch-reducing device to detect them. I can hear this recording clearly, though.

Finally, here is a species I first encountered this past season, the stripe-faced meadow katydid, O. concinnum. It is a specialist in certain kinds of wetlands, and is much less common than the others.

This one I can’t hear at all from more than a few feet away, and I can barely hear it in this recording. I really need the SongFinder for this species. The ticks are more numerous, more separated, and more irregularly spaced, than in the black-leg.

    I can hear them all. I believe the Black-legged would be easiest for me to hear in the field.

    The Striped-faced Meadow Katydid is like the Short-winged Meadow Katydid for me – I can hear it a little with my right ear, and thankfully my left ear’s hearing aid will pick up the song pretty well. I guess that’s OK – I would need glasses to see any of them, and people don’t generally think much about needed those.
