The dataset contains 349 records of Lacewings (Neuroptera) species collected from 2006 to 2019 in continental Portugal. Specimens were detected and captured by direct search of the environment and by using both UV and mercury-vapor lamps to attract the insects. Captured specimens were preserved in 96% ethanol. All captured specimens were identified to species level. The dataset “The InBIO Barcoding Initiative Database: Lacewings (Neuroptera) 02” is part of a group of Neuroptera datasets published by the InBIO Barcoding Initiative (IBI). The first dataset, “The InBIO Barcoding Initiative Database: Lacewings (Neuroptera) 01” (doi.org/10.15468/6cyrxd), has already been made available through GBIF. IBI is funded by the EnvMetaGen and PORBIOTA projects. All specimens are deposited in the IBI collection at the CIBIO (Research Center in Biodiversity and Genetic Resources).

The dataset contains 234 records of Lacewings (Neuroptera) species collected from 2006 to 2019 in continental Portugal (Oliveira et al., 2021). Specimens were detected and captured by direct search of the environment and by using both UV and mercury-vapor lamps to attract the insects. Captured specimens were preserved in 96% ethanol. All captured specimens were identified to species level. Samples of each species were selected for DNA sequencing based on their geographic provenance. From each specimen, one leg (tissue sample) was removed to be used for DNA extraction. The DNA barcoding of these specimens was conducted within the InBIO Barcoding Initiative (IBI), funded by EnvMetaGen and PORBIOTA projects. DNA barcode sequences were deposited in BOLD (Barcode of Life Data System) and GenBank databases. All specimens and DNA extracts are deposited in the IBI collection at the CIBIO (Research Center in Biodiversity and Genetic Resources).

The dataset contains one record of the species Wesmaelius subnebulosus (Stephens, 1836) (Neuroptera, Hemerobiidae), a brown lacewing species, collected in continental Portugal in 2017, and first recorded for the country in Oliveira and Ferreira (2020). The specimen was detected and captured using a light-trap setup. A tissue sample, one leg, was removed to be used for DNA extraction. Sequencing of the 658 bp COI DNA barcode was conducted within the IBI project and the DNA sequence was submitted to BOLD (Barcode of Life Data System) database. The preserved specimen and DNA extract are deposited in the IBI collection at the CIBIO (Research Center in Biodiversity and Genetic Resources).
