Claim: Lepidoptera is a flowering plant species.
Evidence: Lepidoptera (/ˌlɛpɪˈdɒptərə/ LEP-i-DOP-tər-ə, from Ancient Greek lepís "scale" + pterón "wing") is an order of insects that includes butterflies and moths (both are called lepidopterans). 
Lepidopteran species are soft bodied, fragile, and almost defenseless, while the immature stages move slowly or are immobile, hence all stages are exposed to predation. 
The Lepidoptera are among the most successful groups of insects.
