An example is a social parasite that benefits from brood care and access to resources
that are managed by and benefits the host colony. Social parasitism occurs among a
broad variety of insects in which the hosts and the parasites often are closely related,
in some cases forming a sympatric species pair. By contrast, inquilines are animals
that exploit the living space, such as a termite or ant nest, resulting in a commensal
relationship in which one member benefits and the other member derives a reward
or is not harmed (Malyshev 1968). Inquilism often is a precursor to social parasitism, which in turn may be a precursor to cleptoparasitoidism (Askew 1971).
11.3 The Evidence: Distinguishing Predation, Parasitism
and Parasitoidism
Several types of evidence are important for detecting the presence of predation,
parasitism and parasitoidism in the fossil record (Fig. 11.1). Some of this evidence
is associated with particular techniques, such as synchrotron X-ray microtomography (van de Camp et al. 2018), or time-of flight secondary-ion mass spectrometry
