[1] C. schmitzi exhibit polymorphism, with three physical castes - minor, median, and major ("soldier") workers.

It was first collected by the botanist Jan Pieter Schuitemaker and described by the myrmecologist August Stärcke in 1933 as Camponotus schmitzi.

[7] In 1904, Odoardo Beccari suggested that the ants feed on insects found on and around the plant, but may fall prey to it themselves.

Flooding of the ants' nest chamber could result in the death of the developing eggs, larvae, and pupae.

[15] John Thompson suggests that N. bicalcarata may be the only plant species that obtains nutrients through both insect capture and ant-hosting habits.

[18] In addition to Clarke & Kitching (1995), three more theories have been investigated so far to explain the symbiotic relationship between ant and plant.

In an exclusion experiment it was shown that plants without C. schmitzi receive greater herbivory damage, and the ants seem to specifically attack a certain weevil (Alcidodes sp.)

[19] Furthermore, data has been collected that hints to an aggressiveness of C. schmitzi against prey animals that try to escape from the pitchers, thus enhancing the retention rate.

[20] Another mechanism appears to be a host-cleaning behaviour of C. schmitzi: the ants remove debris and mold from the peristome, which thus remains smooth and slippery and has a longer operational lifespan.
