Imprecise excision of the P{SUPor-P} element which deletes part of the second RPA2 exon plus two exons downstream of the original insertion site (1911bp of genomic DNA are deleted).
Homozygotes hatch at the same rate as wild-type embryos, but arrest at the second instar with a normal larval cuticle pattern.
