Male and female boreblasters are similar in appearance. Larvae are stocky and grub-like, distinctive by their patchwork of tan, brown, and white color. They have small, grasping appendages, each ending in a pair of black claws. Adults have longer legs, eye stalks, and wings, which tend to be deep red or orange.
Boreblasters hatch from eggs and spend most of their lives as larvae, feeding on the woody tissue of umbrella trees. After several months of feeding, the larva constructs a burrow and undergoes metamorphosis to develop paired wings, longer legs, and eyestalks.
This species is strictly terrestrial, and in its larval stage it lives in an entirely covered environment burrowing through the woody tissue of plant flora, such as Umbrella trees. However, once they reach maturation and metamorphose into either their breeding or migratory morph, they leave the shelter.
Boreblasters consume the woody vegetation and the fruits of umbrella trees. The larvae depend on umbrella trees for food and shelter. Adults do not feed, because the mouth parts fuse during metamorphosis.
Boreblasters breed by sexual reproduction. Adults disperse to neighboring trees in a breeding frenzy, laying eggs multiple times underneath the leaves of the umbrella tree or in the Umbrella tree fruits before they starve and decompose, giving back vital nutrients to their host tree. The mating system is polygynandrous, meaning that mating occurs among individuals in a social group of multiple males and multiple females. Chemical cues are thought to enable boreblasters to form a mating group. Adults must breed before they starve to death.
Boreblasters produce a toxin that is poisonous to most species. Few predators in the Allurian Forest can tolerate the toxin well enough to consume the eggs or larvae, which have high concentrations of toxin.
