could this be apicalis as well?
sorry if i am showing my ignorance, but i think both heve white hair, and dark wings, and are hard to differentiate

From the iNat link
From the iNat link, there's a slight brown spot on T1 that isn't known to occur in I. apicalis. Otherwise, dark-winged specimens can indeed be difficult to separate, especially males. Females differ in the structure of the head, though it seems males are more separated by mandibular structure or the length of individual flagellomeres (and it does seem that flagellomere I is quite elongate). Bohart & Menke (1963)(1) suggest that the males of I. apicalis have the fore femur reddened basally whereas the only red on I. mexicana legs is occasionally on the hind femur.
