Hilda patruelis is by far the most common of the three species of tettigometrid recorded from southern Africa and is found on a wide range of host plants including groundnuts and wild fig trees Ficus species. Like many other bugs, Hilda attracts ants by expelling droplets of sugary liquid called honeydew. It has been found that on fig trees, the ants attracted by Hilda drive off the parasitic wasps that parasitise the larvae of the fig wasp pollinator and thus benefit the tree by increasing pollinator production. They also increase plant fitness by driving off seed predators as well.
