Many landscapers are familiar with the larger beneficial insects such as lady beetles, praying mantids, lacewings, and flower flies. Although common, parasitic wasps/flies (parasitoids) are examples of landscape beneficials that are typically less recognized because of their small size, and that magnification is needed for best viewing. Also many parasitoids feed unseen on the interior organs within their hosts. Although the majority of parasitoids are found in the two orders mentioned above (Hymenoptera & Diptera), there are more than 50 families that have been identified. Many of these insects do not have distinctive differences in general appearance & therefore attempting to ID the specific species or even family is not practicable for the landscaper or nursery grower. Learning about & being aware of the activity of these less observed but exceptionally important biological control organisms are photographed & reviewed in this blog.

The vast majority of observed landscape parasitoids will be wasp or fly species. (Photo Credit: Steven K. Rettke, Rutgers Coop. Ext.)
