What are flea eggs called? - briefly
The reproductive unit of a cat flea is termed an «egg». These microscopic, oval structures are laid on the host’s environment and hatch into larvae.
What are flea eggs called? - in detail
Flea ova are commonly designated as «flea eggs». In entomological literature the term refers to the embryonic stage produced by adult female Ctenocephalides spp., the primary species infesting mammals.
These eggs possess distinct morphological features:
- Length ≈ 0.5 mm, width ≈ 0.2 mm; oval shape with a smooth chorion.
- Coloration varies from white‑cream to light tan, darkening as embryogenesis progresses.
- Each egg contains a single developing embryo surrounded by a yolk sac.
The reproductive cycle proceeds as follows:
- Female deposits 20–50 eggs per day on the host’s fur, often near the skin surface.
- Eggs fall into the environment, adhering to bedding, carpets, or cracks.
- Under optimal humidity (70–80 %) and temperature (21–27 °C), hatching occurs within 2–5 days.
- Emerging larvae immediately seek organic debris for nourishment before pupation.
Key environmental requirements for successful development include:
- Moisture levels that prevent desiccation of the chorion.
- Absence of direct sunlight, which accelerates egg mortality.
- Presence of organic matter to support larval feeding after hatching.
Understanding the precise terminology and biological characteristics of flea ova assists in designing effective control strategies, targeting the stage most vulnerable to chemical or physical interventions.
