interesting article!


The mutualistic mirid bug P. roridulae bears a thick, anti-adhesive
greasy layer, which is a ‘smart’ surface adaptation for living on the
strongly adhesive surfaces of the plant. The anti-adhesion
mechanism of the mirid bug is based on the cohesion failure caused
by grease. The non-continuous, patch-like pattern of grease found
in potential dipteran prey does not provide sufficient protection
against the plant adhesive. Additionally, the presence of specific
substances in the bug grease targeted to prevent adhesion of
Roridula secretion cannot be entirely excluded. In future studies,
this mechanism should be compared with that of the cuticle
structures of various Heteroptera. Possibly, similar adaptations might
be found in other insect–plant associations. Finally, the cohesion
failure anti-adhesive mechanism might be potentially interesting for
technical developments of novel biologically inspired surfaces.

So, they don't stick because they're greasy little fellows. :wink:
