From: The Hox genes Ultrabithorax and abdominal-A specify three different types of abdominal appendage in the springtail Orchesella cincta (Collembola)

Figure 5

Weak Oc-Ubx(RNAi) phenotype. Low levels of Oc-Ubx are sufficient for appendage fusion, but do not prevent development of walking leg morphology. The appendages on A1 of this larva resemble the legs and have claws at their tips (yellow arrows and inset; compare with the claw at the tip of the thoracic leg marked with a black arrowhead), but their proximal parts are fused (asterisk). The white arrow marks the ventral groove. A1, T2, T3 mark the first abdominal, the second and the third thoracic legs, respectively. Scale bar: 50 μm.
