[3][4] T. gerstaeckeri goes through three stages during its paurometabolous life cycle: egg, nymphal instars and adult.

[2] All blood-feeding arthropods in the genus Triatoma are vectors of T. cruzi, so these numbers are not caused by T. gerstaeckeri alone.

[2] This is usually how T. cruzi is transmitted, but it can also occur during blood transfusion, organ donation or the consumption of contaminated food or drink.

[8] T. gerstaeckeri undergoes gradual metamorphosis (paurometabolous development) which means that there are three stages to its life cycle: egg, nymph and adult.

[5] The eggs of T. gerstaeckeri are white when laid, but turn light pink shortly thereafter.

[5] The highest percentage of nymphs molted when their blood meals were from mammals, particularly squirrels.

[5] The percentage weight gain for T. gerstaeckeri due to blood feeding is highest during the first instar.
