They reproduce by eggs.
The female delivers up to 200 elliptical and white
eggs. Then, their color change to pink as the
embryo evolves. This evolution is completed between
20 and 50 days depending on the temperature. The
eggs are deposited in the ground, wall fissures
and other more or less hidden places.
Since the moment that the vinchuca leaves the
egg until it reaches an adult condition, the insect
experiments many transformations (metamorphic
process that lasts depending on the temperature,
humidity and food).
When the insect is born, it is 3 mm long and
looks like and adult but without wings. In this
first stage of the metamorphic process the insect
is called "chiche pila".
Some weeks later, the nymph changes its skin and
its size increases but still without wings. With
each change of skin the nymph grow bigger and
in the last one the wings appear and the insect
becomes adult. The female becomes adult before
the males.
The whole process lasts around 7 months in good
conditions. The adult insect lives around 15 months.
