A colony of pine needle aphids (Schizolachnus sp.) displaying diverse defense behaviours : body raise, kicking with the hind legs, emission of alarm fluids (containing alarm pheromones) etc... In this species, the two individuals that are at the margin of the colony are typically placed with the head toward the center of the colony. This body orientation behaviour seem also to be a defense mechanism.

A flatworm (Platyhelminthes, Trematoda) of the genus Leucochloridium parasiting a snail of the familly Succineidae (probably Succinea putris or an Oxyloma sp.). The banded pulsating structure visible within the tentacles of the snail are the sporocysts's broodsacs filled with cercariae. The cercariae need to be ingested by a bird to develop up to adult stage in the digestive system of the bird. The change in color and aspect (pulsations) of the snail increases the probability to be eaten by a bird.
