In a recent study, scientists discovered a rare species of fly larva that has evolved a remarkable adaptation to infiltrate termite mounds. This fly larva, known as a blow fly, has developed a “fake termite face” that allows it to blend in with termites and gain access to their colonies. This evolutionary trait is a form of social parasitism or symbiosis,as described in the studies published on phys.org and Popsci.com.
The fly larvae, wich have been observed in southern Morocco, are capable of infiltrating termite mounds and socializing with termites due to their realistic termite masks. This disguise is not just a physical trait but also involves chemical mimicry, as the flies release pheromones that further help them blend in with the termite colony, as noted by Bioengineer.org.
The finding was made by a team lead by Roger Vila, a scientist at the Institute of Evolutionary Biology in Spain. During their expeditions, the team found only a handful of these unique flies, highlighting their rarity.Vila explained that despite multiple attempts to find more of these flies in the same area, thay where only able to locate a few more specimens.
This captivating example of evolutionary adaptation showcases the complex interactions between species and the sophisticated interaction mechanisms employed in nature.

Termite nests are protected habitats rich in food for each species that is cunning enough to enter. Flies’ strategy is one of social integration, which requires extreme morphological, behavioral, and physiological adaptations, according to recent research.
The researchers gathered flight and termite larvae disguised and took them back to the lab, where they found a number of extreme adaptations. For example, the larvae have modified the respiratory holes to act as fake termite eyes and modified sensory organs called papillae, which resemble termite antennae.
Chemical Disguise
Larvae have also developed aroma chemicals to match the unique odor of termites. The villa notes that the team studied the chemical composition of larvae and found they cannot be distinguished from termites in the colony where they live.
“ Their smell is exactly the same,” said the Vila. “In addition,the larvae and termites in certain colonies have a slight difference in their chemical profile that distinguishes them from other termite mounds. This odor is the key to interacting with termites and benefiting from their communal lives. This is a chemical disguise.”
The researchers found that larvae were part of the genus rhyncomya. There are no other members of this group known to carry out this kind of mimicry, so the team suspects the larvae are a newly discovered species. However, the team cannot increase larvae to adulthood to ensure because they all die in the laboratory before they are able to become adults.
Villa notes that there may be elements of termite nests and relationships between the two species they cannot transfer to the lab.
“Their current diet is unknown,and their adult shape remains a mystery,” added the villa.

Interview with Dr. Vila: Unveiling the Mysteries of Termite-Like Flies
Editor: Today, we’re excited to speak with Dr. Vila about a engaging finding involving insects that mimic termites. Let’s dive right in. What drew you to study these uniquely adapted flies?
Dr. Vila: Well, the intrigue started with the extreme morphological and behavioral adaptations these flies exhibit. Our initial interest was sparked because these rare insects had evolved to live symbiotically within termite colonies.
Editor: You mentioned the complexity of these adaptive mechanisms. Can you elaborate on some of these unique adaptations?
Dr. Vila: Certainly! The flies’ larvae have modified respiratory holes to resemble termite eyes, and their sensory organs, known as papillae, mimic termite antennae.This physical change is key to their survival, allowing them to seamlessly integrate into termite colonies.
Editor: Fascinating! You’ve also alluded to chemical adaptations. How do these chemical disguises play into these insects’ strategy?
Dr.vila: Indeed. Our team conducted a detailed study of the chemical composition of the larvae and termites, and we found that the larvae produce unique chemical compounds that mimic the odor of termites. This chemical disguise ensures they aren’t detected as intruders within the colony.
Editor: It’s remarkable how these flies have evolved such intricate adaptations. What further questions do these findings raise in your research?
Dr. Vila: Absolutely. While we’ve made significant strides, there’s still much to uncover. The diet and adult form of these flies remain a mystery. Many elements of their interaction with termites are complex and could not be fully replicated in the lab conditions. Understanding their life cycle and adult morphology is a vital next step.
Editor: Given the rarity of these flies, do you anticipate future searches in the same area or elsewhere?
Dr. Vila: That’s a challenging question. While we did manage to locate a small number of additional specimens in subsequent searches, the rarity of these flies suggests a very localized habitat. Further searches in similar environments could yield more specimens, but it remains a delicate task given their unique ecological niche.
Editor: This research indeed illuminates the sophisticated strategies insects use to survive in their environments. What do you hope the broader scientific community takes away from this discovery?
Dr. Vila: I think the primary takeaway is the complexity and sophistication of interactions between species in nature. These encounters ofen push species to develop remarkable adaptations, providing valuable insights into evolutionary biology and ecological resilience.
Editor: Thank you, Dr. Vila, for sharing your insights and contributing to our understanding of this remarkable natural phenomenon.
Dr. Vila: Thank you for having me. It’s always a pleasure to discuss these intriguing discoveries.
