The boxwood leafminer (Diptera, Cecidomyiidae) has historically been considered a leafminer, but some researchers suggested it induced galls on species leaves. The larvae of create small blister-like galls on leaves, causing tissue hypertrophy and hyperplasia. Histological examination reveals that larvae cause the formation of small blister galls, which involve tissue reorganization in the mesophyll. Unlike typical leafminers, which only disrupt existing tissues, induces the appearance of a neo-formed tissue, near the larval chamber. This tissue, originating primarily from spongy parenchyma cells, significantly increases as the leaf thickens. Various histochemical analyses show that the new tissue contains starch, lipids, terpenes, and proteins, providing evidence of reprogramming in the plant's metabolism. The study concludes that induces rudimentary galls, not simply mines, due to the formation of new tissue, whose cells have cytological characteristics distinct from those found in non-galled leaves. However, despite some gall-like features, it does not create new vascular elements, distinguishing it from more complex galls formed by other gall-inducing species.
黄杨潜叶蝇（双翅目，瘿蚊科）在历史上一直被视为潜叶虫，但一些研究人员认为它会在植物叶片上诱导形成虫瘿。其幼虫在叶片上形成小水泡状虫瘿，导致组织肥大和增生。组织学检查表明，该幼虫会引起小水泡状虫瘿的形成，这涉及叶肉组织的重新组织。与典型的潜叶虫不同，典型潜叶虫只会破坏现有的组织，而这种潜叶蝇会在幼虫腔附近诱导新形成组织的出现。这种组织主要起源于海绵薄壁细胞，随着叶片变厚而显著增加。各种组织化学分析表明，新组织含有淀粉、脂质、萜类化合物和蛋白质，这为植物新陈代谢的重新编程提供了证据。该研究得出结论，由于新组织的形成，这种潜叶蝇诱导形成的是原始虫瘿，而不仅仅是潜道，新组织的细胞具有与未形成虫瘿的叶片中细胞不同的细胞学特征。然而，尽管有一些类似虫瘿的特征，但它不会产生新的维管组织，这使其与其他诱导虫瘿的物种形成的更复杂虫瘿有所区别。
