Hemolymph from mutant larvae produces longer fibres than those from control larvae in a drawout assay testing coagulation.
Homozygous larvae are completely devoid of visible crystal cells.
There are no cone cells present in lzr15 larval or pupal eyes.
Homozygous or hemizygous mutant animals fail to form a normal scab after wounding - a diffuse plug at the wound site is seen instead of the consolidated plug and scab that are normally present 24h after wounding. Only about 15% of mutant larvae survive a normal puncture wound procedure, most of whom are sluggish and flaccid: 85% of wild-type larvae survive this procedure. Most of the cellular responses to wounding appear to initiate in mutant larvae, although they do not progress normally. Epidermal cell fusion occurs, but the syncytium often occupies a greater area than in control larvae. The surrounding epidermal cells also appear to organise around the wound, but their cell borders are slack and wavy, even several cell diameters out from the wound. These epidermal cells can be separated from the overlying cuticle around the wound. Sometimes the edges of the punctured epidermis meet to restore epithelial integrity, but in most cases they do not. Crystal cells are not seen in mutant larvae.
Plamatocytes develop normally in number and pattern.
Eye colour: white. Eyes of mutant flies are shiny compared to controls. The ocelli appear reasonably normal under low power SEM. The eyes have corneal nipples which look much like those of control flies under high power SEM except with more irregularities.
Adult eye has a smooth surface lacking lenses and the ommatidial array. Partial or complete loss of tarsal claws in the leg, a reduction of the third antennal segment and partial loss of female fertility.
