Species undescribed-species-on-crocanthemum (Undescribed Crocanthemum leafminer)
The adult is similar to that of M. capella, but the ground color of the leaf-mining species is markedly brighter orange. The two are also separable on genital morphology.
Known from the eastern/midwestern USA where the larval host plant occurs.
As for the larval host plant.
Larval leaf mines appear in mid- to late May in Iowa, before the plant has flowered; adults emerge straightaway (June) and overwinter.
Crocanthemum bicknellii (Cistaceae) and possibly other spp. of the genus.
Life Cycle
The larva in active feeding mode is a leaf miner; when finished feeding, it goes to the apical part of the stem and silks leaves together to form a chamber inside which it pupates.

M. capella also feeds on Crocanthemum, but it specializes in feeding inside the fruit of the host; therefore, it occurs a few weeks later than the leaf miner.
