Sickle-fly
Sickle-flies are an enormous breed of insect originally native to the Midgewater Marshes of Bree-land. Once thought to be a local menace, these creatures — along with their broods — have begun to spread into other regions of Middle-earth. Whether this expansion is the result of natural migration or the influence of some dark guiding intelligence remains unclear. Like the giant spiders of the world, Sickle-flies appear to be growing steadily in both size and aggression, pushing outward in search of new feeding grounds.
For taxonomic purposes, many large flying insects are classified as varieties of Sickle-fly. These include the massive Glowing Fire-flies of Evendim and Eregion, the giant Hornets of the Southern Old Forest, the Sand-flies of the Cape of Umbar, and several aggressive species of bees and wasps.
Sickle-flies are most often encountered in marshlands, wetlands, and open fields. They are of "normal" difficulty and are generally aggressive, though some will merely threaten until approached. They are notably weak to Beleriand damage, a fact well known among experienced adventurers.
Background
Sickle-flies do not appear in the work of J.R.R. Tolkien and were created for The Lord of the Rings Online. Their presence reflects the game's broader interpretation that many insects and arachnids of Middle-earth exist at unnatural and monstrous sizes.
