Otiocerus Leaf-Hoppers
Otiocerus means “ridiculously superfluous”. This leaf-hoppers attack a wide range of trees, shrubs and grasses. However, the nymphs and adults frequently suck the sap of only one or a few kinds of plants. Besides stunting plant growth by causing loss of sap, some leaf-hoppers introduce a toxin into the plant as they feed; others introduce disease organisms. The thickened part of the antennae is very short and ends with a bristle and are divided into two filaments, which are twisted into weird shapes; it has two simple eyes present on the front of the head; and a suction tube at the bottom. The nymphs feed on fungi while adults live by sucking sap. Many adults are recognizable by their habit of holding up their wings.

Robber Flies
Robber flies have stout, spiny legs, a dense moustache of bristles on the face, and 3 simple eyes in a characteristic depression between their two large compound eyes ( eyes are built of many light-sensitive elements, each with its own refractive system and forming a portion of an image). The mystax helps protect the head and face. The antennae are short, 3-segmented, with a bristle-like structure called an arista. The short, strong proboscis is used to stab and inject victims with saliva containing neurotoxic and proteolytic enzymes which paralyze and digest the insides; the fly then sucks the liquefied meal through the proboscis. Robber flies are opportunistic predators, their diets often reflecting prey availability in a particular habitat. They are impressive predators that typically specialize in flying insects, including wasps, bees, and dragonflies; the prey may be larger than the robber fly itself. Most robber flies frequent sunny, open areas and are active during the warmest parts of the day and year. They perch on branches, logs, stones, or the ground, and rush out to attack when suitable prey flies by.
