Calacobiosis: see symbiosis. 



Cleptobiosis: see symbiosis. 



Dulosis : see symbiosis. 



Coxal file: in some equatic Colcoptera a series of striations just above the 



hind coxa of male and, perhaps, a stridulating organ. 

 Coxal plates: plate-like expansions or dilations of the coxa; specifically in 



aquatic Coleoptera on the posterior pair.

 Ento-parasite: one that feeds within the body of the host. 

 Embioptera: an ordinal term proposed for the Neuropterous family Embidcr.

 Heliophobic: loving darkness: applied to species that shun the light, like, e. g., 



Termites. 

 Heliotactic: light loving: applied to species that live in the open and in day- 

 light. 

 Lestobiosis: see symbiosis. 

 Meron: in Neuroptera ; a sclerite posterior to the coxa and below the epimeron : 



corresponds to the trochantine in Lepidoptera.
