(A) Photo of part of L. ramimaculatus, with a lichen mimicking forewing pattern, CNU-NEU-NN2019004P. (B–C) Photos of the lichen thallus D. ciliiferus, PB23120; thallus segment in (B); and entire thallus in (C). Photos A–C are at the same scale. (D) Photo of a nearly intact lichen thallus of D. ciliiferus, B0474. (E) Photo of L. angustimaculatus with a lichen mimicking wing pattern; CNU-NEU-NN2016040P. (F) Box scatter plots of measurement data displaying lower and upper extremes, lower and upper quartile, median and average (in the blue dotted line) of branch widths of L. ramimaculatus’s forewing pattern (CNU-NEU-NN2019004C) and thallus branch widths of lichen D. ciliiferus (PB23120, B0474) separately. (Black, red and green dots represent measurement results of branch pattern widths of lichen-mimicking lacewing and thallus widths of the two lichen specimens, respectively.) (G) Part of the wing pattern of L. ramimaculatus, with irregular wing spots. (H, I) Portion of the thallus of D. ciliiferus, with irregular spot-like punctiform pycnidia, B0474 (H), B0476P (I) The dark arrows indicate the spots on wing of L. ramimaculatus and thallus of D. ciliiferus. Scale bars: 5 mm in A–E, 1 mm in G–I.
