Nothing is known about the biology of Plagiolepis juddi.


Sharaf et al. (2011) - Plagiolepis juddi appears similar to Plagiolepis exigua but is consistently smaller, TL 1.02 versus 1.23; has a higher scape index, SI 111 versus 84; larger eyes, EL 0.25 x HW versus 0.19 x HW; higher mesosomal length, ML 0.40 versus 0.35. In addition, CI 97 in P. juddi is distinctly longer than broad, while it is broader than long in P. exigua. Furthermore, P. juddi has much sparser pubescence than P. exigua.
