In the case of floral visitors a greater proportion of flies visited the flowers of Eryngium yuccifolium compared to bees and beetles (Fig.
In the case of Eryngium yuccifolium a similar pattern was identified.
The lower levels of floral visitors associated with Eryngium yuccifolium are likely the result of changes in the physical appearance of the inflorescence due to the herbivory by Coleotechnites eryngiella (i.
Although many of the insect families observed visiting the flowers of Eryngium yuccifolium were observed by Robertson (1928) and Molano-Flores (2001), these studies did not provide any quantitative data about the abundance of these families.
