Plate 11- 11. This katydid obviously bears a striking similarity
to a small dead leaf. It is easy to see when the background
coloration is different from the insect. Nonetheless, as dead
leaves do occur among live leaves, this animal is easily
overlooked. Photo by James Adams.Plate 11- 12. This one may take the prize for katydid
camouflage. It looks like a decomposing leaf with only leaf
veins remaining. Photo by Steve Bird.Plate 11- 13. Some katydids appear to rely on “thorns” to protect
them as much as they do camouflage. This large and husky
insect is from southwestern Amazonia. Photo by Sean Williams.Plate 11- 14. This grasshopper (Chromacris trogon) is yet
another orthopteran insect that pretty much looks like the
leaves of its habitat. Photo by Dennis Paulson.Plate 11- 15. Many insects besides katydids and grasshoppers
have evolved to appear to be leaves. This is a stinkbug (family
Pentatomidae). Photo by Dennis Paulson.Plate 11- 16. From a distance this tree frog (Hypsiboas
semilineatus) would appear to be nothing more than a
dangling dead leaf. Photo by Dennis Paulson.chapter 11 evolutionary arms races: more coevolution, more complexity 183
