Notch-horned cleg fly

Notch-horned cleg fly

Haematopota pluvialis

A species of Clegs, Also known as Notch-horned cleg, Dun fly

Easily identifiable by its distinctive wing pattern and its avidity for blood meals, notch-horned cleg fly is a fascinating subject of study. It exhibits sexual dimorphism; females are hematophagous, requiring blood to nourish their eggs, while males primarily feed on nectar. These behaviors change as they mature, with larvae exhibiting predatory tendencies in moist environments where they consume invertebrates before undergoing metamorphosis to take wing.

How to Identify Notch-horned cleg fly?

Rectangle
Life Cycle of Notch-horned cleg fly
Egg After oviposition, the egg of notch-horned cleg fly undergoes a developmental phase where embryogenesis takes place. The eggs are typically laid in batches and are minute in size, variably colored, and oval-shaped.
Larva Upon hatching, the larva of notch-horned cleg fly appears worm-like with a distinct head and segmented body. It generally lacks wings and true legs, growing significantly in size through a series of molts, each stage called an instar.
Pupal Following the last larval instar, notch-horned cleg fly forms a pupa, a non-feeding, often immobile stage where it undergoes transformation. The pupa is compact, with developing adult structures visible externally enshrouded within a puparium.
Adult Emerging from the pupa, the adult notch-horned cleg fly’s development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction.

Habitat Preferences of Notch-horned cleg fly Through Different Life Stages
The larvae of notch-horned cleg fly are typically found in wet, marshy or muddy areas near bodies of water, where they inhabit the soil or detritus and are predators of other small invertebrates. To locate them, one might search around ponds, streams, and wetlands, carefully digging into moist soil and examining under decaying vegetation. The adult notch-horned cleg fly, on the other hand, is commonly seen in open, grassy fields and meadows, especially near livestock or other large mammals, since they feed on blood. Searching for adults would include walking through these areas, looking for notch-horned cleg fly in flight or as they land on animals or humans.

Bite Humans

Notch-horned cleg fly females are known to bite humans, primarily for blood meals which are necessary for egg development. They locate hosts through visual and chemical cues, piercing the skin with their mouthparts. The direct consequence is pain, swelling, and potential allergic reactions for the victim.

Rectangle
Cause Disease in Humans

Notch-horned cleg fly is an insect known for biting which can lead to disease transfer to humans. The bite itself can cause local irritation and allergic reactions. Notch-horned cleg fly is a vector for parasitic and viral pathogens, resulting in diseases such as tularemia. Infection may cause flu-like symptoms, which can escalate to severe conditions if left untreated. Though not a major disease vector, caution is advised in areas where notch-horned cleg fly is prevalent.

Rectangle
Does Notch-horned cleg fly consume human blood?

Notch-horned cleg fly primarily feeds on blood, using specialized mouthparts to pierce the skin and siphon blood directly. This behavior, crucial for female reproduction, can spread diseases like dengue and Zika. Impacts on hosts range from irritation to severe illness. Notch-horned cleg fly bites various mammals, including humans and pets, affecting each host uniquely.
