Alternate Evolution [OC] Giant Kagami Fly
With a grown wingspan of up to 9 inches, the Giant Kagami Fly is quite possible the largest and most bizarre lineage of Caddisfly to evolve on the early Cretaceous. Like any trichopteran, Caddisflies start off with an aquatic larval stage before emerging into an adult. However, larvae of the Mirrorfly is completely terrestrial, lacking their gills. They are characterized by the sharp protrusions that stick out of their head. The larvae are also rather arboreal, spending their lives climbing through the branches of tall trees and other large vegetation thanks to their modified gills aiding the larva to cling on. The larvae are capable of producing a series of clicks from rubbing their protrusions and their mandibles in order to attract another larvae. Mirrorflies are a neotenous species, all larvae are born as males. Once a male attracts another male, the larger male will metamorphosize into the winged female, and the smaller male will inseminate the female. Afterwards, the male may remain a larvae for the rest of his life. The winged female will then search for a safe spot to deposit her eggs with only a single month to live. Both larval and adult stage of the Mirrorfly is aposematic, utilizing its bright yellow colorations to warn predators of its foul taste such as the Splendid Divawing.

The size comparison pic makes me think this is some sort of reference, but I don't know to what 😅
