Biology and morphology of the jelly fungus-feeding sawfly interrupta (Fabricius, 1804) (Hymenoptera: Pergidae: Perreyiinae

This dataset contains the digitized treatments in Plazi based on the original journal article Albertoni, Fabiano Fabian, Reis, Pedro Almeida, Oliveira, Sarah Siqueira (2025): Biology and morphology of the jelly fungus-feeding sawfly interrupta (Fabricius, 1804) (Hymenoptera: Pergidae: Perreyiinae. Journal of Natural History 59 (37 - 40): 2385-2404, DOI: 10.1080/00222933.2025.2568170, URL: doi.org/10.1080/00222933.2025.2568170 ABSTRACT The larvae of the Neotropical sawfly Decameria interrupta (Pergidae: Perreyiinae) are documented here for the first time.

They feed on the jelly fungus Auricularia fuscosuccinea in the Brazilian Atlantic Forest. Morphological characterisation reveals unique elongated tubercles on the thorax and abdomen and substrate-mimicking colouration in the full-grown larvae, while the prepupae undergo significant colour changes (grey/orange to light pink) and construct thick black cocoons. We established new state records for São Paulo and redescribed the adult female with its ovipositor.
