I’ve been noticing a very distinct type of mosquito around my area in Lapu-Lapu City, Cebu. Unlike the usual ones I’ve encountered, this type gives off a strong “rotting meat” smell every time it’s crushed.

Observations

• Size: Small (likely around 4–5mm)
• Color: Full black or very dark, no visible stripes
• Smell: Always present even when mosquito is not fed. Smell is strong, organic, and unpleasant (like decay)
• Behavior: Found indoors, often active at night
• Frequency: I’ve encountered this same type multiple times over months, among hundreds of mosquito kills

Hypothesis

It’s unlikely that the smell comes from blood content or gut bacteria, since:

• It’s consistent across unfed specimens
• Other mosquitoes don’t share this smell

I suspect the source is the cuticle hydrocarbons or internal body chemistry, possibly species-specific. It’s notably different from Aedes aegypti or albopictus which are more common here.
