plural koinobionts
- biologyA parasitoid whose host continues to feed and grow after parasitization.
Not many koinobionts are ectoparasitoids, although a number of ichneumonoids (e.g. Tryphoninae; Adelognathinae; Polysphinctini; some Rogadinae) and a few eulophids are (Plate 1).

1994, Bradford A. Hawkins, Pattern and Process in Host-Parasitoid Interactions, Cambridge University Press, 2005, Digitally printed paperback, page 95, Koinobionts are as rich, or richer, on hosts on herbs as on hosts on trees for endophytics, whereas on exophytics they tend to be richest on trees (in natural habitats at least).
As in most ecological groups of parasitoids, saproxylic species can be divided into koinobionts and idiobionts according to the classification proposed by Haeselbarth (1979) and further developed by Askew and Shaw (1986). The main feature of that classification is whether or not the host insect continues its development after it has been paralysed. Koinobionts do not paralyse or immediately kill their hosts, allowing them to instead continue feeding and growing.
