The team found many Mertensia eggs and larvae, but never any adults.
The team found that Mertensia larvae as small as 0.

has monitored bees crawling over Mertensia
Algific talus slopes harbor populations of over 60 vascular plant species that are disjunct in Iowa from wet woods and bogs in northern or western boreal forests, including Adoxa moschatellina, Carex media, Cornus canadensis, Linnaea borealis, Mertensia
paniculata, Poa paludigena, Pyrola asarifolia, Rihaimnus alnifolia, Ribes hudsonianum, Streptopus roseus, and Viola renifolia (Thorne 1964, Frest 1982).
Morris (1996) found that significantly more pollen was removed from robbed flowers one day after anthesis in the bumble bee-robbed Mertensia
paniculata as compared to unrobbed flowers.
In mid-April, an area between the secondary trail and the cypress swamp supports a large number of Mertensia
virginica (Virginia bluebells).
The chosen species were Claytonia lanceolata ("spring beauty," Portulacaceae), Erythronium grandiflorum ("avalanche lily," Liliaceae), Mertensia brevistyla ("bluebell," Boraginaceae), Delphinium nuttallianum ("Nelson's larkspur," Helleboraceae), Lathyrus leucanthus ("peavine," Fabaceae), Potentilla pulcherrima ("cinquefoil," Rosaceae), Eriogonum subalpinum ("buckwheat," Polygonaceae), Ipomopsis aggregata ("scarlet gilia," Polemoniaceae), Campanula rotundifolia ("harebell," Campanulaceae), and Seriphidium vaseyanum ("mountain sagebrush," Asteraceae).
Claytonia lanceolata, Erythronium grandiflorum, and Mertensia brevistyla formed an early cohort; Delphinium nuttallianum, Lathyrus leucanthus, and Potentilla pulcherrima formed a middle cohort; and Eriogonum subalpinum, Ipomopsis aggregata, Campanula rotundifolia, and Seriphidium vaseyanum formed a late cohort.
Interestingly, a color change with age occurs in other species of Mertensia
and in at least 11 other genera in the borage family (Weiss 1995).
