“Spiked Magician” (Saga pedo)

Also known as the predatory bush cricket, the spiked magician is a species of sagine bush cricket (Saginae) which occurs from southern Europe and western Asia from the Iberian peninsula across central Europe and central Asia to China. Sage pedo is known to inhabit both dry and wet meadows, pastures, scrubland, and even grain fields/vineyards. True to its common name Saga pedo is indeed predatory and will feed on a range of other insects. It earns its other common name due to the “enchating” way it moves its forelimbs as it approaches its prey.

Orig. Comb: Locusta camellifolia Fabricius 1775
Explanation of Names
Species name from Greek camelo camel, plus Latin folius (?) a leaf (1), referring to the shape of the wings, presumably–held over the back to form a camel-like hump(?).
Size
Circa 45-55 mm
Identification
Forewings form cup over abdomen, many conspicuous veins. Pronotum has two shallow grooves. Both sexes stridulate “katy-did, katy-didn’t” at dusk into night. Song varies geographically.
Range
e US (mostly: TX-FL-MA-IA) - Map - SINA
Habitat
Deciduous forests–often heard, but seldom seen, since mostly lives in forest canopy.
Season
Midsummer to frost. July-October (Michigan), July-September, or November (North Carolina)
Food
Foliage of deciduous trees, and shrubs(?)
Life Cycle
Eggs are inserted into loose bark or young stems of trees and hatch in spring. One brood per year. Both sexes stridulate, males more loudly. Song varies geographically. Flightless, but may glide to lower branches of trees (2). Sometimes seen perched on shrubs. Does not come to lights frequently (pers. obs., P. Coin).
Remarks
One of the few North American insects, perhaps, memorialized in verse. Below is an excerpt from Oliver Wendell Holmes, Sr.’s poem, To an Insect (1831), full text available from Project Gutenberg:

I LOVE to hear thine earnest voice,
Wherever thou art hid,
Thou testy little dogmatist,
Thou pretty Katydid

Genus: Macroxiphus

Macroxiphus is a genus of unusual katydids (Tettigoniidae) that are distributed throughout South East Asia and Micronesia. Members of Macroxiphus are unique in that their larvae are exceptional ant mimics, and use their mimicry to trick potential predators into thinking they are harmful ants. Macroxiphus spp. will lose this disguise as they move on into adulthood.

Armoured Bush Cricket (Acanthoplus discoidalis)

… AKA Armoured Ground katydid, Bradyporinae, a subfamily of the katydid family (Tettigoniidae). The species is native to parts of Namibia, Botswana, Zimbabwe and South Africa. 

Acanthoplus discoidalis is a wide-bodied, flightless species that typically grows to a body length of about 5 cm. The pronotum bears several sharp, conical spines. The mandibles, or main biting jaws, are powerful; they can inflict a painful nip and they permit the insect to feed on material such as tough herbage or carrion.

Another defense against predators is reflex bleeding (also called “autohaemorrhaging” in which the insects squirt haemolymph from pores in their exoskeleton, achieving a range of a few centimetres…

rikuyomi  asked:

While shooting, do any of the bugs or other wildlife you encounter show hostility towards you?

That very much depends on the type of insect of course and on how threatened they feel. I certainly don’t set out to provoke them, but there is no denying a defensive pose or threat display usually makes for a more interesting photo.

I have been stung by Nocturnal Hornets while doing night shooting (see that tumblr post HERE) and I have certainly been intimidated by Predatory Hornets (Vespa velutina) while trying to photograph them and even when not trying to photograph them…..

The Stinging Nettle Slug Caterpillars of the Limacodid Cup Moths are passively hostile by default and even the slightest brush against them inflicts a seriously painful sting. This can happen while searching for them amongst foliage or while adjusting the foliage around a subject so as to get a clear shot. I have experienced this many times…..

And the Chalcosiine Day-flying Moth Caterpillars (Zygaenidae) express their displeasure by excreting droplets of cyanide from the tubercles on their skin….

Otherwise, hostility usually takes the form of threat displays which in themselves are harmless but intended to strike fear in my heart and confusion in my mind and send me scurrying away with my tail between my legs…..

I usually try not to handle my subjects, but when I do it is to give some sense of scale or to relocate them from hazardous situations. Particularly with the larger insects, although they are not intentionally harmful in themselves, the sheer size of their anatomy means sharp claws and strong jaws have drawn blood on occasion as well….
