Chromosome-level genome of the brown lacewing Micromus angulatus (Stephens, 1836) (Neuroptera: Hemerobiidae).

The brown lacewing Micromus angulatus (Stephens), a member within the subfamily Microminae of the family Hemerobiidae, is a globally distributed species and an important predatory natural enemy of various agricultural and forestry crop pests. Despite its global distribution and agricultural significance, genomic resources for the development of novel pest management strategies for M. angulatus and the family Hemerobiidae remain limited. Here, we present the first high-quality chromosome-level reference genome for M. angulatus, achieved through PacBio HiFi and Hi-C technologies. The assembled genome spans 1.29 Gb, with scaffold N50 of 63.78 Mb, and complete BUSCO score of 97.00%, containing eight pseudochromosomes, demonstrates a high degree of continuity. Functional annotation identified 13,250 protein-coding genes, and repetitive sequences, which account for 83.65% of the genome, were also characterized. This comprehensive assembly offers a robust reference for in-depth research on the genetic basis of predation and adaptability in M. angulatus, supports further research into the understanding the genetic diversity within Hemerobiidae, contributing to the broader knowledge within the group and its related species.
