In the male, wing discs proliferate rapidly in the eighth instar and continue proliferating. A conspicuous peripodial epithelium forms and the hemopoietic organs break down and disappear completely by the prepupal stage. Whereas in female, the wing discs remain as in the seventh instar, without proliferation of cells inside. Therefore, there is no peripodial epithelium formation and the hemopoietic organs are still attached to the wing discs. Finally the entire wing discs transform into a plain, thick epidermis in the prepupal period.{{Cite journal |last=Niitsu |first=Shuhei |date=2003 |title=Postembryonic development of the wing imaginal discs in the female wingless bagworm moth Eumeta variegata (Lepidoptera, Psychidae) |url=https://onlinelibrary.wiley.com/doi/abs/10.1002/jmor.10116 |access-date=2021-08-22 |journal=Journal of Morphology |volume=257 |issue=2 |pages=164–170 |language=en |doi=10.1002/jmor.10116|url-access=subscription }}{{Cite journal |last1=Niitsu |first1=Shuhei |last2=Lobbia |first2=Saori |last3=Izumi |first3=Susumu |last4=Fujiwara |first4=Haruhiko |date=2008-07-01 |title=Female-specific wing degeneration is triggered by ecdysteroid in cultures of wing discs from the bagworm moth, Eumeta variegata (Insecta: Lepidoptera, Psychidae) |url=https://doi.org/10.1007/s00441-008-0615-7 |access-date=2021-08-22 |journal=Cell and Tissue Research |volume=333 |pages=169–173 |language=en |doi=10.1007/s00441-008-0615-7|url-access=subscription }}

In 2018, the complete mitochondrial genome of the moth was sequenced using a nanopore sequencer as a single long read. It is the second report of a complete mitochondrial genome of psychid species.{{cite journal |first1=Kazuharu |last1=Arakawa |first2=Nobuaki |last2=Kono |first3=Rintaro |last3=Ohtoshi |first4=Hiroyuki |last4=Nakamura |first5=Masaru |last5=Tomita |date=2018 |title=The complete mitochondrial genome of Eumeta variegata (Lepidoptera: Psychidae) |journal=Mitochondrial DNA Part B |volume=3 |issue=2 |pages=812–813 |doi=10.1080/23802359.2018.1495119|pmid=33474332 |pmc=7799889 |doi-access=free }}

The natural parasites of the species include: Apanteles claniae, Aulosaphes fujianensis, Chouioia cunea, Exorista japonica, Nealsomyia rufella, Sarcophaga caudagalli, and Sclerodermus guani. Pathogens are Bacillus thuringiensis and Nucleopolyhedrosis virus.{{Cite web |title=Eumeta variegata |url=https://www.cabi.org/isc/datasheet/16415 |access-date=2021-08-22 |website=www.cabi.org |language=en}}
