  • Seemingly oblivious to its own potential demise, an ornamental moth caterpillar (Rhuda sp.) carries on about its daily business while a tiny parasitoid Chalcidid wasp (Conura sp.) rides piggyback. These wasps are among a multitude of related species which utilize caterpillars (and their pupae) as living hosts for their brood. After depositing its eggs, the wasp’s larvae develop within the caterpillar’s body, carefully consuming its non-vital organs until they are ready to emerge. In this way, the caterpillar will be kept alive just long enough to insure the wasp larvae are able to complete their life cycle. Soberanía National Park, Panama.

  • A potter wasp (Omicroides singularis) returns to her nest with a paralyzed caterpillar. Each perfectly crafted urn will be filled with a dozen or so caterpillars before she deposits a single egg and seals the entrance. The developing wasp larvae will feed on the caterpillars before pupating and emerging as an adult. Sarawak, Malaysia (Borneo).

  • A female pompilid wasp (Eragenia congrua) hauls a paralyzed spider (Corinna sp.) towards her nest, after having neatly amputated its legs to make the transport of her victim easier. This will not be food for her, but for her offspring. Her nest consists of a hole in the soft bark of a tree, and once depositing the spider inside she will lay a single egg, which upon hatching into a larva will consume the still-living host. Yasuní National Park, Ecuador.

  • Tiny, ubiquitous, and comprising many thousands of species, parasitoid wasps extract a heavy toll on their hosts, with many species responsible for keeping other insect populations in check. Here, a female wasp (Anastus sp.), just a few millimeters in length, drills her ovipositer into the eggshell of an Atlas Moth (Attacus atlas), the world's largest moth. Her developing larvae will consume the contents of the egg and pupate therein before emerging as adults. Sarawak, Malaysia (Borneo).

  • Unable to fly with a load many times her own weight, a female Thread-waisted Sand Wasp (Ammophila beniniensis) hauls a large caterpillar which she has paralyzed with her sting. She is seeking a burrow she has prepared in advance and, even though it may be a considerable distance away, she shows a remarkable orientation ability even though there may be numerous obstacles in her path. Once placed inside, with the burrow sealed shut by small rocks and its entrance hidden from potential thieves, the ill-fated caterpillar will serve as live food for the single egg the wasp has deposited along with it. Fianarantsoa, Madagascar.

  • After detecting the presence of a wood-boring grub with her antennae, a female ichneumon wasp drills through the tree bark with her ovipositor to deposit an egg on the insect's body. Halmahera, North Maluku, Indonesia.

  • A butterfly caterpillar (Cupha erymanthis) standing guard over a clutch of parasitic wasp pupae that recently hatched from its body. Having been impregnated by eggs from a female wasp, the larvae develop within the caterpillar, consuming its flesh as they grow. In order to keep their host alive, the wasp larvae are careful to avoid all vital organs and the caterpillar thus appears and behaves rather normal until the larvae eventually emerge. In a similar vein to the mind-controlled zombie ants, the wasp larvae also secrete some cocktail of hormones that modify the behavior of the caterpillar, in this case it is induced to stand guard and protect the wasp pupae from predators or other parasitic wasps until it eventually dies of starvation. Sarawak, Malaysia (Borneo).

  • Covered in gaudy colors to warn of her painful sting, a female velvet ant (Odontomutilla grossa) scurries about the rainforest floor in search of a nest to parasitize. These are not ants at all but actually a type of wasp (family Mutillidae) in which the females are completely wingless. Eggs are laid in the nests of other wasps or bees where they feed on the larvae of their host. Sarawak, Malaysia (Borneo).

  • In the insect world, even having a vicious sting isn’t enough to always save you from some larger predators. Here, in the dry spiny forest of southern Madagascar, a wasp has fallen prey to a giant robber fly (Microstylum sp.). With fast wings, excellent eyesight, and piercing mouthparts, robber flies catch other insects in mid flight and suck out their insides like a juice pack. Berenty Private Reserve, Amboasary, Madagascar.

  • It’s hard at first glance not to be fooled by the appearance of this wasp-mimicking katydid (Aganacris nitida), which is modeled after a stinging thread-waisted wasp (Eremnophila spp.). To enhance the effectiveness of this masquerade, the katydid also copies the wasp’s quick erratic movements, as most other katydids (especially camouflaged ones) move rather slowly. Katydids possess no chemical or otherwise painful defenses, and make for particularly good meals for predators, which is the driving force behind their remarkable disguises. Yasuní National Park, Ecuador.

  • In possession of one of the most painful stings in the insect world, tarantula wasps (Pepsis spp.) are avoided by just about every animal in the forest. This makes them a great thing to be mistaken for, especially if you happen to be an otherwise defenseless katydid such as this (Aganacris velutina). The katydid not only mimics the wasp’s distinctive coloration of a shiny black body with bright orange wings and antennae, but also its quick and jerky movements, making it appear decidedly ‘un-katydidlike’. This is particularly amazing considering katydids are family of insects normally renowned for their remarkable camouflage colorations. Canandé Reserve, Esmeraldas, Ecuador.

  • Assassin bug (Zelurus sp.) which mimics a spider wasp. Yasuní National Park, Ecuador.

  • Shag-carpet Caterpillar (Prothysana), one of two species that, aside from their curious appearance, exhibit a remarkable form of mimicry. Tiny parasitoid wasps are known for extracting a heavy toll on caterpillars: their larvae devour a caterpillar from inside out, emerging once they are ready to turn into adult wasps and leaving their distinctive white cocoons in the process. At a glance, the white dorsal hairs of Prothsyana look exactly like these wasp cocoons, so much so that the wasps themselves likely avoid laying their eggs in this caterpillar, believing that it has already been eaten. Yasuní National Park, Ecuador.

  • Patents don’t exist in nature, and no species has a monopoly on clever designs. Here, a mantidfly (Mantispidae) makes use of spiny raptorial front legs to catch prey, much like a praying mantis. Mantidflies are actually more closely related to lacewings and ant-lions, and like their relatives they have no chemical or otherwise painful defenses against predators. Because of this, many mantidflies mimic wasps and in this particular species it appears to specifically mimic an orange Night Wasp (Provespa anomala). Anyone who has ventured into the Bornean rainforest after dark knows that night wasps are to be avoided: they possess an extremely painful sting that can cause skin necrosis. Danum Valley, Sabah, Malaysia (Borneo).

  • With their spring-loaded jaws capable of snapping shut at over 200km/h, trap-jaw ants (Odontomachus sp.) have some of the fastest predatory strikes in the animal kingdom. However, this isn’t their only weapon: they also possess a powerful wasp-like sting that can either subdue prey or serve as an effective deterrent against any animal foolish enough to disturb their nest. There are over 70 species distributed throughout the tropics, shown here is one of the largest: O. tyrannicus from the steamy lowland jungles of New Guinea, its mandibles retracted and ready to strike. Papua, Indonesia.

  • Sun Glass Frog (Hyalinobatrachium aureoguttatum), male hiding on the underside of a leaf. The pattern on the back of this species mimics a cluster of the frog's eggs, which help to deter attacks by predatory wasps. Esmeraldas, Ecuador.
    cld1811675.jpg
  • Not all gaudy appearances are a disguise – some are simply a warning. Quite a number of moth species deceptively mimic the shape and color of stinging insects (such as wasps and bees), but others such as this Window-winged Moth (Glanycus coendersi) don’t appear to resemble any particular model. Instead, the bright aposematic coloration of this insect is believed to be a bold advertisement of its distastefulness. This defense works as an effective signal to predators, thereby allowing the moth to exploit other lifestyle advantages such as foraging during daylight hours (e.g. this is a diurnal species) while other moths must retreat into hiding until nightfall. Sabah, Malaysia (Borneo).

  • A dead leaf mantis (Deroplatys cf. lobata) standing guard over her egg sac. Such behavior might enable her to deter parasitoid wasps from destroying her brood, a common threat for mantises. Maliau Basin Conservation Area, Sabah, Malaysia (Borneo).

  • A column of nomadic Asian army ants (Aenictus laeviceps) carry their developing larvae to a new temporary nesting site. Ants of the genus Aenictus are specialized predators on other social insects, including wasps, bees, termites, and other ant species. Sarawak, Malaysia (Borneo).
