Here we have the Small Black Ant (Lasius niger) again. But what is he up to this time, you may wonder?

I found him on my Fatsia Japonica with these strange yellow ‘bumps’ which are in fact another species of scale insect called Viburnum Cushion Scale (Lichtensia viburni). And you guessed it, he is eating sweet sugary poop again.

The scale insect has piercing and sucking mouthparts which it uses to feed on sap obtained from the host plant (in this case Fatsia Japonica) which it secretes as waste called honeydew. Ants are attracted to the honeydew and feed on it. Ants will even act as body guards, protecting the scale insects from predatory attacks. This ant spent quite sometime with the scale insect, touching it with its antennae.
