I’ve come across several of these large, shield-backed katydids on my trip. There is a green version of this insect, but I have yet to see one.
Sooty Longwings are capable of feeding on a number of plant species. However, unlike its eastern relatives, this insect shows carnivorous tendencies and can watched hunting in shrubs at night with a flashlight.
They are attracted to lights and capture and eat other insects that come to the lights. I’ve seen a few walking around paved roads at night, probably scavenging for food.
Mostly found in the desert, they are active from June through November and found in a variety of shrub species such as creosote and mesquite.
The males call on warm nights with a loud, pulsating trill, punctuated by brief pauses. I enjoy the intricate lines and patterns on these katydids – it’s almost like a work of art.
