FlyBase curator comment: this entry is used to capture phenotypic information when the particular allele (or allele combination) used by the author could not be determined but the context of the experiment suggests that the phenotype being described is some kind of loss of function.
dendrite & filopodium & larva
Homozygotes show defects in larval dendrite development; mutants have abnormally long bundled filopodia that run parallel to each other at the end of the dendrite.
