提取物由二斑毛蛛的成熟幼虫制成。也只从他们的头上。将该提取物注射到异株荨麻的叶基部。在150次注射全幼虫浸提液的12次注射中观察到注射部位生长，在50次注射仅头部浸提液的9次注射中观察到注射部位生长。这种生长不象D.荨麻疹，但包括增厚的实质，没有核不规则。显然，动物学对虫瘿形成的贡献并不局限于产卵时引入的刺激物或仅由新孵化的幼虫分泌的刺激物，但细胞分裂是由一种化学物质促进的，该化学物质存在于宿主特异性的囊螨的完全发育的幼虫中。
Extracts were made from mature larvae of Dasyneura urticae. and also from their heads only. This extract was injected into leaf bases of Urtica dioica. Growth at the site of the injection was noted in 12 out of 150 injections with whole larva extract, and in 9 out of 50 with head-only extract. This growth did not resemble normal galls of D. urticae, but consisted of a thickening of the parenchyma, with no nuclear irregularities. Evidently the zoological contribution to gall formation is not confined to stimulants introduced at the time of oviposition or secreted only by newly hatched larvae, but cell division is promoted by a chemical present in fully grown larvae of a host-specific cecidomyid.
