-Megarhyssa ovipositors, in addition to being used to deposit eggs on the crew of the ships they capture, can also be used as stingers, injecting venom into the target. They can control the composition of their venom, and concoct several different vena at will, all of which are fiendishly complex, littered with //polydnavira// endogenous to the individual megarhyssa, and ever evolving to avert the development of natural antivena; megarhyssae will often deploy aphrodisiac formulae when courting others. Megarhyssa venom can be incredibly potent, with a single bubble's worth of some formulae being able to incapacitate a dragon.+Megarhyssa ovipositors, in addition to being used to deposit eggs on the crew of the ships they capture, can also be used as stingers, injecting venom into the target. They can control the composition of their venom, and concoct several different vena at will, all of which are fiendishly complex, littered with //polydnavira// (a family of insect vira integrated into wasp genomes) endogenous to the individual megarhyssa, and ever evolving to avert the development of natural antivena; megarhyssae will often deploy aphrodisiac formulae when courting others. Megarhyssa venom can be incredibly potent, with a single bubble's worth of some formulae being able to incapacitate a dragon.
  
 When deploying venom, megarhyssae produce orders of magnitude more of it than the relevant glands can hold, requiring them to use their bubble as a holding chamber, whereupon it inflates into a sphere instead of a flat circle; this often requires them to discard unused venom by “spraying” it out of their ovipositors. When deploying venom, megarhyssae produce orders of magnitude more of it than the relevant glands can hold, requiring them to use their bubble as a holding chamber, whereupon it inflates into a sphere instead of a flat circle; this often requires them to discard unused venom by “spraying” it out of their ovipositors.

 Megarhyssae prefer to eat fruit, cereals, and root vegetables, as well as most any other starchy food; honeydew and sweet potatoes are particular delicacies to them. However, they are omnivorous in practice, especially after long stretches of privation. Megarhyssae prefer to eat fruit, cereals, and root vegetables, as well as most any other starchy food; honeydew and sweet potatoes are particular delicacies to them.

-===== Life cycle =====+===== Oviposition ===== 
 + 
 +The most fascinating aspect of the megarhyssan reproductive cycle is the ovipositing behavior of the adult female wasps. Once a female has successfully mated, she must first locate a host inside a suitable substrate, or place one there herself. Megarhyssae seem to prefer sapient and sophont prey. Exactly how females sense these hosts in a manner suitable for triggering an egglay trance is currently unknown, but experts speculate that it is either via olfaction or auditory cues, in both of which realms their sensory apparatus is particularly keen. 
 + 
 +Female atratans have the longest ovipositors of any megarhyssa clade, ranging from about 22-26 feet (6.68-8.02 m) long, and can parasitize larvae burrowed up to 24 feet (7.36 m) in hardwood. A membranous pouch at the abdomen's tip holds the looped ovipositor while the female lays eggs. This provides support and stability while the stylus tip penetrates the wood. 
 + 
 +The ovipositor is inserted straight down into the substrate so that it will eventually enter the prey item's burrow at an exact right angle. Females choose appropriate burrows for ovipositing so that the tip of the ovipositor will just reach the surface of the host. 
 + 
 +Once the female is ready to oviposit her eggs, she rotates segments 8 and 9 of her abdomen and unfolds her intersegmentary membranes so that they form a disc or bubble, depending on the clade, 3½ feet (1 m) or more in diameter. The surface of this disc produces a lytic secretion that disintegrates wooden substrates and facilitates her ability to insert her ovipositor. After she lays her ectoparasitoid eggs on the surface of the prey item, she completes the same rotational movements to remove her ovipositor from the wood, and the stylus returns to its resting position. 
 + 
 +Due to the long length of the ovipositor in female megarhyssae, completion of this cycle takes over one hour. During this period the females are particularly vulnerable to predators due to their egglay trance and physical anchoring to the substrate; therefore, the risk of predation is positively correlated with ovipositor length, and others will guard them during the process. Guardian megarhyssae usually stand in a high stance with their tails and ovipositors either raised straight up or curled under their bodies, ready to attack — and often charged with venom — in either case.

 +====== Life cycle ======
  
 Megarhyssae often, but don't always, mate as part of the process of Emergence from the substrate into which they were oviposited, at which point their life is considered to begin, as their larvae and pupae are nonsapient. Males tend to swarm the sites of female Emergence, detected by the chewing sounds they make as they eat through the substrate into which they were laid, and mating outside that event or immediately thereafter is rare. Virgin females lay haploid eggs, which will Emerge as their sons; mated females lay diploid eggs, which will Emerge as their daughters. Their eggs are ectoparasitoids, oviposited directly on the host, one egg per prey item. While still inside the eggs, the megarhyssae develop into larvae. Upon hatching, the larvae emerge and begin feeding on the host. Megarhyssae often, but don't always, mate as part of the process of Emergence from the substrate into which they were oviposited, at which point their life is considered to begin, as their larvae and pupae are nonsapient.

Line 41: Line 53:
 While mating is often impersonal among megarhyssae, some mate for a term of years or for life, though such pairing is not usually known to impede the practice of casual sex with others; megarhyssae are known to engage in recreational sex, and non-courtship displays of their genitalia or coremata, with a casualness unmatched except perhaps by safìr. While mating is often impersonal among megarhyssae, some mate for a term of years or for life, though such pairing is not usually known to impede the practice of casual sex with others; megarhyssae are known to engage in recreational sex, and non-courtship displays of their genitalia or coremata, with a casualness unmatched except perhaps by safìr.

 Various studies have suggested that these wasps communicate with one another and interpret the environment using a variety of sensory cues ranging from auditory (including ultrasound), to olfactory, to chemoreception, to vibration detection. However, researchers have yet to determine the precise senses used. Most of what is known about the megarhyssan sensory structure has been gained from observing their reproductive cycle. Various studies have suggested that these wasps communicate with one another and interpret the environment using a variety of sensory cues ranging from auditory (including ultrasound), to olfactory, to chemoreception, to vibration detection.

 Megarhyssae, both standard and tauric, are space pirates who board starcraft and return them to their territory, thence to use the crew for incubation, as their original prey species are long extinct. Their own starcraft are notable for massive interior spaces and control surfaces meant to be manipulated by their mouthparts and/or ovipositors. Tauric megarhyssae are often leaders of their bands. Some bands are known to board ships and engage in superfluous courtship displays for the sole purpose of entrancing safìr with their pheromones and leading them back to their own craft. Megarhyssae, both standard and tauric, are space pirates who board starcraft and return them to their territory, thence to use the crew for incubation, as their original prey species are long extinct.
