“…Dendrorycter marmaroides Kumata 1978 is similar with respect to the presence of two lateral bulges (dorsal and ventral), but these are pointing backwards. Phyllocnistis has a small spinneret (Cerdeña et al 2020;pers. comm.…”

Fossil leaf-mining caterpillars from amber are firstly described as the new species Phyllocnistis cretacea from Upper Cretaceous Myanmar amber and Phyllonorycter inopinata from Eocene Baltic amber. Both show typical traits of leaf-miners, and specifically, of later instars of caterpillars of their respective genera. The findings give further evidence for these being quite old and conservative genera of Gracillariidae. These are basal Ditrysia which retained the larval feeding and mining live mode. The findings also represent direct fossil evidence of individual stages of hypermetamorphosis known from extant Gracillariidae. The finds from the Upper Cretaceous and their putative identifications give direct evidence for a minimal geological age for the genus Phyllocnistis (Phyllocnistinae) and, by indirect conclusion based on their divergence, also for the genus Phyllonorycter in a sister clade (Lithocolletinae). It also predates mining habit closer to the time of radiation of their angiospermous host plants.

“…In the mined pinnules, boundaries between mined and unmined areas are obscure because the frass trails frequently cut across the secondary leaf veins without distorting them. This can be interpreted in two ways: the larvae might mine only epidermal cells and they did not consume mesophylls, as in the case of Phyllocnistis Zeller (Lepidoptera: Gracillariidae) 54 , 55 ; otherwise, the larvae could mine mesophyll avoiding vascular tissues (e.g., some agromyzid flies 56 ). The latter strategy is possible because the mesophyll of ferns is anatomically well-differentiated into palisade and spongy tissues 57 .…”

The Late Triassic saw a flourish of plant–arthropod interactions. By the Late Triassic, insects had developed all distinct strategies of herbivory, notably including some of the earliest occurrences of leaf-mining. Herein we describe exceptionally well-preserved leaf-mine trace fossils on a Cladophlebis Brongniart fern pinnule from the Momonoki Formation, Mine Group, Japan (Middle Carnian), representing the oldest unequivocal leaf-mines from East Asia. The mines all display a distinctive frass trail—a continuous meandering line, which later becomes a broad band containing spheroidal particles—demonstrating larval development. Although the shapes of the frass trails are generally comparable to those of Lepidoptera or Coleoptera, they cannot be unequivocally assigned to a specific extant leaf-mining taxon. Furthermore, elemental analyses by X-ray fluorescence (XRF) reveals that the frass trail comprises phosphate coprolites. The quantitative variations in P, S, and Si between coprolites and leaf veins may reflect physiological processes (e.g., consumption, absorption, and excretion) mediated by plant chemicals. Our findings reinforce the idea that leaf-mining had become a pervasive feeding strategy of herbivorous insects by the Late Triassic.

We provide new information on Neotropical Phyllocnistis Zeller (Gracillariidae) associated with Baccharis (Asteraceae) in the Andes region. Two new species are described, P. canta Cerdeña & Farfán, n. sp. and P. elongata Cerdeña & Farfán, n. sp., from the western slopes of the Andes of Peru between 2,000 and 3,000 m elevation, both associated with Baccharis latifolia (R.&P.) Pers. The type locality of P. baccharidis Hering is confirmed; immature stages were found at 1,300 m feeding on Baccharis tucumanensis Hook. & Arn. in Quebrada las Higueras (Tucumán, Argentina). Four new locality records for P. furcata Vargas & Cerdeña are provided, extending its distribution by 450 km to the north of the type locality.
