~50 infective juveniles
This series documents a small-scale observation rather than a controlled scientific experiment designed to quantify infection or mortality.
Explore the eight episodes and follow the observations from the first encounter to a new generation.
01
—
MEET THE FUNGUS GNAT
Before exposure
Meet the host before the experiment
begins.
02
—
THE HUNTERS ARRIVE
0 hours after exposure
The infective juveniles enter the environment containing the host.
03
—
THE SEARCH
12 hours after exposure
Infective juveniles move through the environment.
04
—
FIRST CHANGES
24 hours after exposure
Early changes become visible in the host.
05
—
CHANGES IN THE HOST
12-24 hours
Movement decreases as the infection progresses.
07
—
A NEW GENERATION BEGINS
48 hours after exposure
Inside the cadaver, development has progressed dramatically.
06
—
INSIDE THE HOST
12-24 hours
Infective juveniles can be seen through the transparent cuticle.
08
—
A NEW GENERATION
72 hours
A new generation of infective juveniles emerges
from the host and moves back into the environment.
