Nature is so beautiful… look at this beautiful display of the prickly rose gall. These galls are a parasitic sack formed by the cynipid wasp. The wasp, like many other parasitic insects, uses the wild rose plant as a safe haven for its offspring. They inject a substance into the plant and then lay their eggs in it, as the larva grows, so does the gall and that is what the larva uses as a food supply and as a protection sack until they are ready to join the world. You would think this type of parasitic infestation would be damaging to the host plants, but research shows that the plants are not affected by these types of infestations.
I find galls very interesting and these ones in particular are one of my favorite… the wasp that created these galls was surely an artist… it used the leaves to create the perfect bed for its children <3 here is another perfection of Nature’s artistry…

Diplolepis polita is the wasp’s scientific name. These galls show up in the California wild rose (Rosa californica) at the Carpinteria salt marsh; I love showing them off to tour attendees. Russo discusses the species extensively in Field Guide to Plant Galls of California and Other Western States.
I’ve always wondered if the spines (which are flexible at first, then become brittle with age) represent the wasp repurposing the genetic code that produces the rose’s thorns.
