While the term "roach with lashes" might conjure up humorous images thanks to viral internet trends, it also points to a fascinating, albeit less conventional, subject: the Metoecus paradoxus beetle, a peculiar insect with a unique parasitic lifestyle. Furthermore, the phrase also invokes common fears and misconceptions about cockroaches and their potential interactions with humans, including the rather unsettling thought of them consuming eyelashes. Let's delve into both aspects to separate fact from fiction.
Metoecus paradoxus is a beetle belonging to the family Ripiphoridae. It's a relatively small insect, measuring approximately 10 mm in length. Its appearance is characterized by a dark head and body, contrasted by paler, orange-colored elytra (hardened forewings). Notably, these elytra are pointed and do not completely cover the abdomen, contributing to its distinctive look.
The most remarkable aspect of M. paradoxus is its parasitic relationship with Vespula vulgaris, the common wasp. This beetle is primarily a parasitoid, meaning it ultimately kills its host. The life cycle unfolds as follows:
For a parasite to successfully infiltrate a host colony, it must avoid detection and subsequent rejection. M. paradoxus, like other parasitic social insect species, employs sophisticated strategies to achieve this. One key mechanism is chemical mimicry.
Studies have shown that M. paradoxus mimics the cuticular hydrocarbon profile of its host, the common wasp. Cuticular hydrocarbons are chemical compounds found on the surface of insects, and they play a crucial role in colony recognition. By mimicking the host's chemical signature, the beetle effectively camouflages itself, reducing the likelihood of being identified as a foreign intruder. In fact, one study found that M. paradoxus shares around 91.1% of compounds with V. vulgaris. This remarkable chemical similarity allows the beetle to move undetected within the wasp nest, increasing its chances of successfully parasitizing wasp larvae. Parasites employ various mechanisms, including chemical mimicry and chemical camouflage, to mimic the host colony's odor. When the M. paradoxus beetle penetrates the V. vulgaris host, it is vital that it avoids being detected. The same goes for all parasitic social insect species. These beetles seem to avoid being detected by mimicking the cuticular hydrocarbon profile of their host, the common wasp.

In 2020, a video posted by American rapper Megan Thee Stallion on Instagram brought the term "eyelash bug" into the spotlight. The video depicts Megan and a friend encountering an insect on a wall. Megan jokingly identifies it as an "eyelash bug," commenting on its seemingly prominent eyelashes. The insect then flies away, eliciting screams from Megan and her friend. A second recording shows comments of people reacting to it and identifying it as M. paradoxus as Megan's friend shows her images of it, to which Megan replies, "Bitch, that is her. Look at them damn lashes! ^
While the identification of the insect in Megan Thee Stallion's video may have been M. paradoxus, the term "eyelash bug" is not a recognized scientific term. The video, however, highlights the common human fascination (and often fear) of insects and their potential interactions with us.
The thought of cockroaches consuming human eyelashes is a common fear, fueled by the general disgust and unease that many people feel towards these insects. While it's true that cockroaches are opportunistic feeders and will consume a wide variety of organic matter, the reality of them targeting eyelashes is more nuanced.
Cockroaches are known for their adaptability and their ability to survive in diverse environments. They are omnivores, meaning they will eat both plant and animal matter. Their diet includes meats, sweets, and starches, but they are also known to consume less conventional items such as book bindings, wallpaper, pet fur, dead skin, soap, garbage, and feces. They are attracted to anything with protein or moisture: think pet fur, shed skin, and nails. German and Oriental cockroaches, in particular, like to lurk in dark crevices near trash bins or damp basements. There, they’ll happily snack on everything from leftover food and spilled drinks to paper, glue, and other surprising household materials.
While cockroaches can and will eat fingernails, skin, and hair (including eyelashes) if the opportunity presents itself, it's not their preferred food source. These items contain protein, which cockroaches need, but they are not as appealing as other readily available food sources. Human hair and nail clippings are the favorite foods of cockroaches and that explains why cockroaches live with us in our homes.

The scenario in which cockroaches would actively seek out eyelashes on a living person is rare. It would likely only occur in cases of severe cockroach infestation where other food sources are scarce. It is more likely that cockroaches will nibble on nail clippings and loose hairs found on the floor than attempt to eat fingernails or eyelashes on a living, breathing person. That would be risky business for a cockroach. Not to say it doesn’t happen. It has happened in rare situations where there is an extremely large cockroach infestation and not enough other food to feed them.
The myth that "roaches eat only babies’ eyelashes, because sleeping adults will brush away the cockroaches while babies can’t" is also untrue. Babies (except for newborns) can roll over and squirm around just as well as adults.
Beyond the eyelash-eating myth, cockroaches pose real concerns for humans.
