Which family displays a lacelike dorsum in adults and spiny black nymphs?

Explanation:
Lace bugs, family Tingidae, are known for a dorsum in adults that looks like delicate lace—the wings and thorax form a reticulate, netted pattern that gives a lacelike appearance. In the immature stages, Tingidae nymphs are often dark and spiny, giving them a distinctly different, spiky look from the lacy adults. This combination of a lacelike adult dorsum and spiny black nymphs is characteristic of Tingidae and helps distinguish them from the other families. The other groups lack this particular pairing of lacework in adults and spiny, dark nymphs, so they don’t match both traits together.
