Answer:
"Black-veined white" butterfly is the common name of the Aporia crataegi.
Specifically, the large, striking butterfly gets its common name from its dramatically contrasting white wings veined in black (for males) or brown (for females). The butterfly's scientific name reflects its preference for hawthorns (Crataegus spp) as a food plant. Other favorites include blackthorns (Prunus spinosa) and shadbushes (Amelanchier spp).
