Morphology
The phrase is a straightforward taxonomic noun phrase combining 'order' (a taxonomic rank) with the name 'Ephemerida' (a group of insects); its meaning — the taxonomic order containing those insects — is directly derivable from the constituents. Although somewhat technical, this compositional pattern (order + taxon name) is common across languages and thus a B1 learner who knows the two words would understand the MWE.
Etymology
Order Ephemerida comes from the Greek word ephemeros, which means 'lasting a day'. People used it for mayflies because adult mayflies live only a short time, so the name means a group of 'short-lived' insects.
