Natural History Photographs

Since insects inhabit a world of plants, interactions between them are guaranteed, whatever the form they take. For instance, insects will land on plants for having a nice platform for inspecting the environment. Such interactions are opportunistic and accidental, quite different from the other plant-animal interactions I describe. Yet there are also some interactions that are in between the extremes of accidental and purposeful interactions. Here are a few examples, which don't fit well in the other categories I delineated.

Plants creating favorable habitats

In areas with good plant cover, plants always form the habitat for insects. However, sometimes this generic relationship becomes more specific. Presence of epiphytic mosses on tree trunks, as shown below, may affects humidity of the local environment, which may promote growth of algal cells - food for springtails. The alternative explanation is that the higher humidity is the reason why the springtails cluster on the edges of the patches with liverworts.
