{A photograph} genuinely confirmed a bagworm moth caterpillar and its “little log cabin” cocoon.
In 2019, {a photograph} shared to Reddit was stated to indicate a bagworm moth caterpillar — a small, seemingly whiskered insect — carrying a number of moss-covered sticks on its again, forming what seemed like a “little log cabin.”
Joe Rominiecki of the Entomological Society of America stated bagworm moth caterpillars are real bugs that “construct covers over themselves out of sticks or different particles.” Collectively, they’re known as “case bearers.”
Rominiecki despatched Snopes a blog post revealed by the ESA in 2020 that featured the bagworm moth caterpillar, together with a number of different “costumed bugs.” In accordance with the submit, the bugs “assemble whole wood homes to put on.” The society wrote:
Through the entirety of their larval improvement interval, bagworm moth caterpillars reside inside protecting instances they construct round themselves out of exactly positioned twigs and thorns. (Some even resemble tiny log cabins!) These instances have made the research of bagworm moth larval progress charges troublesome, because the caterpillars by no means totally emerge from the housing. Whereas finding out the connection between case measurement and caterpillar measurement in Eumeta crameri bagworm moths, researchers found that the length of the largest stick in a case directly corresponded to the larva’s developmental stage. Larval floor space roughly doubles at every instar, requiring bagworm moth caterpillars to increase their housing as they develop.
David Cheng, a researcher on the College of Florida’s Division of Entomology and Nematology, stated he didn’t consider any elements of the photograph had been exaggerated. The image confirmed a “typical spiral sort of bag,” he stated.
“The truth is, there are greater than six various kinds of these ‘baggage’ which were outlined, and there might be much more,” Cheng added, referring to the next pictures taken on the Smithsonian Nationwide Museum of Pure Historical past:

“As their identify suggests, bagworms’ larvae usually construct bag-like instances from leaves, stems, and detritus, which they spin along with silk,” Cheng wrote. “Thus far, the bagworm household (Lepidoptera: Psychidae) has been comparatively poorly studied. Nevertheless, for many of the recognized taxa, their life cycles are sometimes round one or two years.”
Other than the bugs’ baggage, Cheng stated entomologists had been notably fascinated by their sexual dimorphism.
“In most taxa, males are winged, identical to different moths, whereas grownup females are wingless (over half of the recognized species). Females of some species are even much less cell, being vermiform [worm-like] into maturity and missing legs, wings, eyes, antennae, and mouthparts completely… which is actually bizarre, proper?”
On condition that two consultants confirmed the authenticity of the picture, we rated this declare as “True.”
