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.
褐蛉Micromus angulatus（斯蒂芬斯）是褐蛉科微褐蛉亚科的成员，是一种全球分布的物种，也是多种农林作物害虫的重要捕食性天敌。尽管其全球分布且具有农业重要性，但用于开发针对褐蛉和褐蛉科的新型害虫管理策略的基因组资源仍然有限。在此，我们通过PacBio HiFi和Hi-C技术，展示了首个高质量的褐蛉染色体水平参考基因组。组装后的基因组跨度为1.29 Gb，支架N50为63.78 Mb，完整BUSCO得分97.00%，包含八条假染色体，显示出高度的连续性。功能注释鉴定出13250个蛋白质编码基因，还对占基因组83.65%的重复序列进行了表征。这种全面的组装为深入研究褐蛉捕食和适应性的遗传基础提供了有力参考，支持进一步研究褐蛉科内的遗传多样性，有助于更广泛地了解该类群及其相关物种的知识。
