Ingesting 20E caused decreased feeding in larvae, exosmosis of ecdysial fluid, failure of removal of the old head capsule or exuvium, morphogenesis into a deformed pupa, bulging of the hindgut, and supernumerary instars.
These observations suggest that ecdysial leg position may be retained after ecdysis, although Gaban & Farley (2002) also observed that Paruroctonus mesaensis (Stahnke 1957) pulls its appendages medially during ecdysis.
