Diplolepis mayri is a gall inducing insect (Hymenoptera: Cynipidae) causing galls on wild roses (Rosa sp.) in the Western Palaearctic. Diploleis mayri is less frequent on rose shrubs than D. rosae. Its galls show in their external morphology resemblance to the mossy rose gall or robin's pincushion (Diplolepis rosae), but the surface of the gall is less covered and the emergences on it are more spine-like. It may appear together with D. rosae on the same host plant. Galls of D. mayri are multilocular and its chambers have thicker walls than found in D. rosae.
In the winter time galls of D. mayri are often opened by predators just as are the galls of D. rosae. These predators may be birds as in the case of other Cynipidae galls: for D. rosae the lesser spotted woodpecker (Picoides minor), for Andricus spp. and Neuroterus spp. the great tit (Parus major).
In its galls occurs the same parasitoid assemblage as known for D. rosae. The most abundant parasitoids of both galls are Orthopelma mediator, Torymus bedeguaris, Glyphomerus stigma and Pteromalus bedeguaris. One inquiline species, Periclistus brandtii also occurs in both galls... Wikipedia →

Possible
About 20% of wildlife watchers report a Diplolepis mayri sighting in Sierra Nevada National Park on a given day, based on 22 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 103rd most-seen of the 479 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
June
In that month about 30% of wildlife watchers report a Diplolepis mayri in Sierra Nevada National Park on a given day, against under 5% in October to March, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Diplolepis mayri sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 parks where we can rate Diplolepis mayri sightings, Sierra Nevada National Park has the highest daily chance: about 20%. Next come Sierra de Guadarrama National Park (Spain, under 5%).
Same genus: Diplolepis
The closest relatives of the Diplolepis mayri that you can see in Sierra Nevada National Park (genus Diplolepis) are Mossy Rose Gall Wasp (about 10%) and Smooth Pea Gall Wasp (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Diplolepis mayri is recorded against all the insects logged in Sierra Nevada National Park (22 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
