#549 - Requena Katydid

Requena sp. (Fam. Tettigonidae)

Yet another Orthopteran from my yard. I’ve been rather startled at the variety - and rather more by the number of Orthopteran families I’ve never heard of before now. I guess my knowledge of the order was sorely lacking, as well as out-of-date.

Many katydids are carnivorous. One Australian species even mimics female cicada noises, to lure males to their doom. I have no idea what this one eats, but since the forelegs aren’t fearsomely spined, probably a harmless herbivore. On the other hand, Requena verticalis is one of the katydids known to feed the female a large sperm-mass meal at the end of mating - a useful protein supplement.

#548 - Cone-headed Bush Cricket

image

Conocephalus sp. (Fam. Tettigonidae), although my reference book says you don’t get them down here in the SW.

Somewhat pointy-headed katydids with long skinny hind legs, and frequently with a set of brown and white stripes down the back of the neck. The antennae can be three or four times longer than the body, but this one seems to have suffered an injury at some point.
