These traits (temporary paralysis and use of the host’s burrow as 
a nest) are often regarded as primitive, since they resemble the 
condition in structurally generalized wasps such as Scolioidea. (Evans, 
I 958 a,b). However, they might equally well be derived traits, 
suited to the ecology of their prey, and likely to reduce the success 
of satellite flies.
