Wyvern Wasp

The Wyvern Wasp is a parasitic insect known for its lethal reproductive strategy. It specifically targets the eggs of certain wyvern and wyrm species, penetrating into them with precision. This ultimately leads to the destruction of the egg, ensuring that the wasp's larvae can thrive.
Found exclusively in the eastern region of Arkynshire, particularly near the arid boundary of the Duskfire Desert, the wyvern wasp has adapted to a narrow ecological niche. Its lifecycle and feeding habits remain intricately linked to the health and population of the selected wyvern and wyrm species it infests. The specificity of their target species has an impact on the broader biodiversity of the area.

Basic Information

Anatomy

Adult wyvern wasps are characterized by their large, robust mandibles, which serve to defend themselves against predators while they search for host eggs. Despite their smaller size compared to wyverns or wyrms, these mandibles possess remarkable strength and are able to cut through dragonkin skin. These formidable mouthparts serve as crucial weapons for fending off predators, allowing the wasp to defend itself effectively against threats. Additionally, the mandibles are used during competitive interactions with other wyvern wasps, as they engage in aggression to establish dominance over territory and resources. Males typically have larger mandibles than females; however, both still possess remarkable strength.
Hunting for host eggs can be particularly challenging, especially when confronted with Sandwyrms, whose bodies are armored with protective scaleplates. These scutes shield most of a sandwyrm's body, leaving very few vulnerable areas for the wasps to exploit.
In addition to their impressive mandibles, wyvern wasps boast an exceptionally hard exoskeleton composed primarily of chitin. During their larval and pupal stages, these wasps incorporate calcium carbonate into their exoskeleton, further enhancing its durability. This unique combination makes the waps resilient against crushing forces and difficult to cut through. Moreover, their exoskeleton protects them against various chemical agents that humans might use to eliminate these pests. However, they do have a vulnerability: uncalcinated diatomite, a powdery substance, can be abrasive and create microscopic abrasions on the wasp's exoskeleton. These tiny cuts may lead to increased water loss, ultimately resulting in dehydration and death.^[3]
Unlike some of their relatives, wyvern wasps do not possess a traditional stinger. Instead, they have a specialized barb-like organ known as an ovipositor. This appendage is not connected to venom-producing glands, rendering it incapable of delivering venom like that of many stinging insects. The primary function of the ovipositor is to penetrate and lay eggs within a host egg, ensuring the survival of the wasp's offspring. In rare and extreme situations, the wyvern wasp may employ this barb-like appendage to inflict pain on a potential threat, but it is purely mechanical and is incapable of injecting venom.

Genetics and Reproduction

Wyvern wasps exhibit a unique reproductive strategy characterized by external fertilization. During this process, both male and female wasps engage in a parasitic reproductive method, wherein they implant their respective gametes into the eggs of some species of wyverns and wyrms. If the wasp egg is successfully fertilized, it will develop into a larva that feeds on the nutrient-rich yolk of the host egg. This provides the larva with ample sustenance as it matures within the egg, ultimately killing the host embryo.
In cases where fertilization of the wasp egg fails, a phenomenon may occur. The host egg may incorporate some of the wasp's DNA during its development into an embryo. This genetic merging results in the creation of a hybrid subspecies of the wyvern or wyrm. While these hybrid dragonkin species do not look much different than their normal counterparts, this does result in a beneficial outcome for them. Remarkably, when searching for suitable host eggs for laying their own, wyvern wasps seem to ignore these hybrid eggs. This behavior potentially indicates that these wasps have the ability to distinguish suitable eggs, possibly suggesting that they might be sensitive to specific pheromones or other chemicals present on or within these eggs.

Growth Rate & Stages

After successful fertilization of the wasp egg, it very quickly develops into a larva, usually within a couple of days. The timing of the wasp's egg-laying significantly impacts the larva's growth. If the wasp lays its eggs before the host egg has a chance to develop its embryo, the wasp larva can feed on as much of the nutrient-rich yolk as possible.
However, if the host egg has already progressed to the point of developing an embryo, the wasp larva will feed intensely on the available yolk, often consuming enough to starve the host embryo. This parasitic strategy ensures the survival of the wasp larva, even at the expense of the host.
Once the larva has completed its growth phase, it enters the pupal stage while still encased within the egg. This transitional period is crucial as it allows the wasp to undergo significant development while in the safety of the eggshell. Upon maturation, the pupa utilizes its strong mandibles to break free from the egg. This emergence is a critical moment, as they are vulnerable to predators from both the host's parents and others in the environment. In the wild, it is impossible to determine if an egg has been infested with a wyvern wasp larva. Only once the pupa breaks through the eggshell does it become apparent.
If the pupa successfully escapes, it instinctively moves to burrow into the sand or silty ground. Here, they adopt a predatory lifestyle, ambushing small insects much like an antlion larva.^[2] Over a month and a half, it undergoes several molts, gradually transforming into an adult wyvern wasp.
After completing its pupal stage, the wasp undergoes its final transformation into adulthood. At this point, it develops wings that enable it to fly. The adult wasp actively searches for the eggs of wyverns or wyrms, completing the cycle by laying its eggs parasitically within these host eggs.

Dietary Needs and Habits

The wyvern wasp primarily feeds during its larval and pupal stages. During these critical development phases, the wasp consumes a diet rich in calcium, which plays an essential role in the formation of its robust exoskeleton. This chitin armor is subsequently fortified by the accumulated calcium, ensuring the wasp is well-equipped for its survival.
