caps⁰²⁹³⁷ embryos show discontinuous dorsal trunk formation.

64% of homozygous embryos fail to hatch, though all those that do hatch develop into normal looking larvae. Very few (3%) survive to adulthood. In homozygous mutant embryos, the SNb enters the ventral muscle field and the RP neurons defasciculate normally. Furthermore, RP1, RP3 and RP4 properly synapse with their respective target muscles, whereas the RP5 axons stall, show enlarged growth cone like structures and fail to contact the target muscle. Instead the RP5 axons are split and found also in direct contact with the transversal nerve.
