The evolution of diverse and novel morphological traits is poorly understood, especially how symbiotic interactions can drive these adaptations. The extreme diversity of external traits in insect-induced galls is currently explained by the Enemy Hypothesis, in which these traits have selective advantage in deterring parasitism. While previous tests...
Integrative taxonomic practices that combine multiple lines of evidence for species delimitation greatly improve our understanding of intra- and inter-species variation and biodiversity. However, extended phenotypes remain underutilized despite their potential as a species-specific set of extracorporeal morphological and life history traits. Primar...
Insect-induced galls are novel structures that serve as habitat to whole communities of associate arthropods that include predators, parasitoids, and inquilines. Galling insects are generally under-described, but their associate communities, which can include many specialist organisms, are virtually unknown, particularly in the southwest United Sta...

The North American sawfly Setabara histrionica (Tenthredinidae: Heterarthrinae) is previously known only from adult collections but has been hypothesized to feed upon trees in the genus Prunus. We discovered a population of leaf-mining sawflies in Washington on Prunus emarginata and identified it as S. histrionica using combined morphological and m...
We report here the immature stages and natural host plants for three species in the so-called "Taygetis clade" of the nymphalid butterfly subtribe Euptychiina, Taygetis echo (Cramer, 1775), Taygetis sosis Hopffer, 1874, and Pseudodebis valentina (Cramer, 1779). The study was carried out at Finca Las Piedras in Madre de Dios department, Peru. Tayget...
We describe here for the first time the complete immature life cycles and shelter structures of two Neotropical skipper butterflies in the subtribe Moncina, Troyus phyllides (Röber, 1925) and Thoon ponka Evans 1955, along with new natural host plant records for these species at Finca Las Piedras, Madre de Dios, Peru. Four eggs and a preantepenultim...
Here, we describe and name a new nymphalid butterfly species in the subtribe Euptychiina. Caeruleuptychia thaliana Nakahara & Piovesan, n. sp. is proposed by incorporating three independent sources of evidence: adult external morphology,
DNA sequence data, and early stage biology. Caeruleuptychia thaliana n. sp. is known from two sites in the Amaz...
The immature stages of two euptychiine butterflies (Nymphalidae: Satyrinae), Paryphthimoides terrestris (Butler, 1867) and Magneuptychia iris (C. Felder & R. Felder, 1867), are described herein and their natural host plants are documented. Notes on the immature stages of these two species were included previously in an unpublished dissertation, alt...

USDA APHIS Plant Protection and Quarantine’s Identification Technology Program (ITP) is pleased to announce the release of Sawfly GenUS, Edition 1. Sawflies are a unique group of wasp-like herbivorous insects, many of which are economic pests in North America. While most sawflies generally maintain low popul...
Plant associations are newly recorded for three tenthredinid species in the Pacific Northwest. A single Monardis pulla D.R. Smith, 1969 emerged from a chamber inside a cynipid gall on Rosa nutkana C. Presl. (Rosaceae). This is the first plant association record for M. pulla. Two Aphilodyctium fidum (Cresson, 1880) emerged from a stem and cynipid ga...
In the present study, the immature stages of the Neotropical euptychiine butterfly Taygetis rufomarginata Staudinger, 1888 are described and illustrated in detail for the first time, from specimens collected in Madre de Dios department, Peru. The morphology of all four instars, the egg and pupa, are described and the duration of each stage is recor...
