Allomerus decemarticulatus

Once an insect lands on the plant, the closest ant will immediately surface and grab on to a leg, antenna, wing, or some other appendage of the prey.

Froghopper

Many species resemble leafhoppers, but can be distinguished by the possession of only a few stout spines on the hind tibia, where leafhoppers have a series of small spines.

•

Many adult Cercopidae can bleed reflexively from their tarsi, and the hemolymph appears to be distasteful; they are often aposematically colored (see photos).

Ibaliidae

An apical tubular process is present on the second tarsomere of the hind leg.

Leptoglossus

Like members of some other genera in the family, these bugs have leaflike dilations of the hind tibia.

Organ pipe mud dauber

They are fairly large wasps, shiny black with pale hind tarsi.

Palpada megafemur

Its coxae and trochanters are black; its femora is black except becoming brownish to orange on its apical 1/4, and shiny except for the mesofemur, which is sparsely gray on its apical 2/3; tibiae are orange; tarsi are orange.

Syntelia

The characteristics of the family and genus include geniculate antennae with 3-segmented club, elongate body, narrowly separated coxae and tarsi with bisetose empodia.

Tridactylidae

They have several unusual features, for example, the posterior femora are greatly enlarged, being strongly adapted for leaping; in some species those hind femora actually are larger than the abdomen.

•

The posterior tibiae also bear articulated spines near their tips, plus spurs longer than the hind tarsi, which may be entirely absent or else are at best vestigial, having only a single segment.

Xyelidae

The family is characterized by the appendages of the head, which are remarkable in that the antennae and palpi are nearly leg-like in structure, with a long basal segment followed by a series of tiny segments, as in the tibia-tarsus.
