Leaf-mine: A distinctive mine primarily above mid-rib, with irregular short lateral offshoots into leaf blade. Pupation external (Spencer, 1972: 51 (fig. 172), 55; Spencer, 1976: 270, 271 (fig. 486)). Branched, whitish, upper-surface corridor; main axis overlying the midrib; side branches overlying the main lateral veins. (In Campanula and Phyteuma the mine is much less branched, sometimes nothing more than a corridor on top of the midrib). Frass in rather long strings. Usually the mines begins as a long and narrow, shallow, tortuous lower-surface corridor that ends upon the midrib but otherwise is not associated with the leaf venation. Often this initial corridor is filled with callus, and then even less conspicuous. Pupation outside the mine (Bladmineerders van Europa). The mine is also described and illustrated in British leafminers.     Mines of Liriomyza strigata on Sonchus.

Puparium: Posterior spiracles each with an ellipse of 10-12 bulbs (Spencer, 1972: 55. Comments: A polyphagous species recorded here from 240 host plant genera in 35 plant families worldwide and 47 host plant genera in 15 plant families in Britain. Alyssum saxatile is treated as Aurinia saxatile (Golden Alison) and Arabis arenosa is treated as Arabidopsis arenosa (Sand Rock-cress) by Stace (2010). Diagnostic protocols to distinguish L. strigata from bryoniae, huidobrensis and sativae, may be found at www.csl.gov.uk/specialInterest/liriomyza.pdf. Chrysanthemum coronarium is treated as Glebionis coronarium (Crown Daisy); Chrysanthemum segetum is treated as Glebionis segetum (Corn Marigold); Leontodon autumnalis is treated as Scorzoneroides autumnalis (Autumn Hawkbit); Lychnis flos-cuculi is treated as Silene flos-cuculi (Ragged-Robin); Lycopersicon esculentum is treated as Solanum lycopersicum (Tomato); Senecio fluviatilis is treated as Senecio sarracenicus (Broad-leaved Ragwort) and Stachys officinalis is treated as Betonica officinalis (Betony) by Stace (2010).
