In the present study, we report phoresy of the Chernetid pseudoscorpion Sphenochernes camponoti (Beier, 1970) on flies in the Caatinga biome in Northeastern Brazil.
This makes it very difficult to study mayflies in their natural habitat and record instances of phoresy.
To our knowledge there are no previously published reports of chironomid phoresy among crayfish.
To visualize the form of phoretic selection and because phoresy scores are binomially and not normally distributed, the cubic spline fitness function estimation procedure was also performed (see Schluter 1988).
From tertiary amber records, we know that, 40 million years ago, phoresy was already established (Ross 1997; Poinar et al.
This represents only the tenth record of phoresy of Anoplura by Diptera and the fifth record by Muscidae.
Although the primary function of phoresy is dispersal, phoretic associations may be complex (Binns 1982; O'Connor 1982; Houck & O'Connor 1991).
(2005) found that Elpidium, another ostracod genus, used phoresy on frogs for transport from bromeliad to bromeliad in Brazil, like Dero worms.
these mites do not parasitise their beetle hosts but use them as a means of transport only, otherwise known as phoresy (Szymkowiak et al.
