Goals / Objectives
1. Produce taxonomic revisions and phylogenetic analyses of families, genera, and species, including new taxa, of Trichoptera from around the world, but with special emphasis on the New World fauna. These revisions will include diagnoses, descriptions, illustrations, and keys to species, including larvae when possible. The resulting revisions will form the taxonomic foundation for future studies in ecology, behavior, and the application of Trichoptera in water quality assessment and monitoring. 2. Maintain an authoritative collection of Trichoptera, to include a computerized database of specimens. 3. Produce illustrated, interactive, web-based keys to the adults and larvae associated with revisionary studies and maintain a databank of specimen images. 4. Train graduate students in modern systematic methods (primarily morphological, but also molecular approaches in collaboration with colleagues). This training will also include aspects of specimen preparation, curation, and electronic data and image management as well as field collecting components. Specific projects for the next 5 years include: monographic evision and phylogenetic assessment of the genera Cernotina and Cyrnellus (L.M. Camargos, PhD dissertation), monographic revision and phylogenetic assessment of the Smicridea nigripennis species group (L.E. Rázuri-Gonzales, PhD dissertation), catalog of world microcaddisflies (Hydroptilidae) and description of Neotropical species (R.E. Thomson), catalog of Neotropical caddisflies (R.W. Holzenthal and A.R. Calor), monographic revision of the genus Nectopsyche (R. W. Holzenthal), contiued exploration of the caddisfly fauna of Ecuador (R.W. Holzenthal, R.E Thomson, B. Ríos-Touma), phylogeny of caddisflies (R.W. Holzenthal, K.M Kjer).
Project Methods
Established methods for taxonomic study of Trichoptera include clearing male genitalia in KOH or lactic acid, followed by examination and illustration of structures under a stereomicroscope. Taxonomy is based on male genitalia, but it is also important to examine and illustrate female genitalia and larvae, when available. Digital photography is used to capture images followed by the use of digital illustration and image editing programs (Adobe Illustrator and Photoshop) to enhance and accelerate illustration of specimens. An added advantage of electronic image capture is the ease with which images can be posted on a website. The descriptive taxonomic software DELTA is used to automate the traditionally laborious task of writing taxonomic descriptions and identification keys. DNA barcoding is used to corroborate or support species hypotheses using an integrative taxonomic approach where needed (Pauls et al., 2010).Specimen data gathered in conjunction with revisionary and monographic studies will be incorporated into the existing BIOTA database at the University of Minnesota Insect Collection. This database is designed for recording and analyzing locality or collection-based survey data. The University of Minnesota Insect Collection has computer and bar coding hardware dedicated to the museum's collections management program and BIOTA databases. Barcode labels (code 49, 4 mil polyester, 8 x 14 mm) are used to label, database, and track Trichoptera specimens in the BIOTA database. The methods proposed for conducting phylogenetic analyses are in accord with standard practices including discrete morphological data coded in a character matrix using the software Mesquite followed by model-based phylogenetic inference and Bayesian analysis (Wright and Hillis 2014).

Impacts
What was accomplished under these goals? Caddisflies, or Trichoptera, are important components of freshwater ecosystems where they participate in many levels in the aquatic food chain and act as biological indicators of water quality. This research project focused on the systematics and taxonomy of caddisflies. Its main objectives were to provide taxonomic revisions and descriptions of the species, to maintain an authoritative research and reference collection of specimens, to produce keys and other guides to identification, and to train graduate students in systematics and taxonomy. The taxonomic research associated with this project resulted in the description and revisions of 100s of new species of caddisflies and led to an understanding of their phylogenetic relationships and their utilization as biological indicators of water quality. 2021 was a challenging year for this research project due to the COVID-19 pandemic and the projects direct dependence on the University of Minnesota Insect Collection. In spite of this, positive accomplishments were achieved. While no new material was formally accessioned into the collection, about 10,000 specimens await physical placement in the collection's cabinets. Caddisfly specimens in the collection total 658,883 individuals including over 200 holotypes and representing 3,413 species. The collection maintains its status as one of the most important collections of Trichoptera in the world. All specimens are entered in the collection's Specify database. Holzenthal participated in one research trip to Ecuador in September (prior to the appearance of the Omicron COVID-19 variant) to continue research on caddisfly faunistics of the country with Dr. Blanca Ríos-Touma. Material was collected from 18 separate localities spanning 2 elevational gradients from ca. 3800-300 meters and represents about 1500 specimens collected. Specimens have all been labelled and identified to species. These are awaiting the descriptions of new species, databasing, and accessioning into the collection, work planned for 2022. Holzenthal and Dr. Ríos-Touma continued an second research project on the genomics of the fauna with Dr. Paul Frandsen, Brigham Young University, and Dr. Steffen Pauls, Senckenberg Research Institute and Natural History Museum, Germany. A subset of specimens from the September trip were preserved in 95% ethanol and set aside for DNA extraction and sequencing. This research will look at genomic data to study adaptations of Neotropical caddisflies to high Andean environments. One paper on this topic was published. Dr. Robin Thomson, curator of the collection, continued work on a world catalog of the microcaddisflies and on various taxonomic studies with colleagues in Ecuador, Panama, and Pennsylvania. She submitted a grant request to NSF CAREER program in June, 2021 for $962,000 to study the phylogeny of the microcaddisfly family Hydroptilidae. The grant was awarded in January, 2022 and will continue for 5 years.

The taxonomic research associated with this project resulted in the description and revisions of 100s of new species of caddisflies and led to an understanding of their phylogenetic relationships and their utilization as biological indicators of water quality. 2020 was a challenging year for this research project due to the COVID-19 pandemic and the projects direct dependence on the University of Minnesota Insect Collection. In spite of this, positive accomplishments were achieved. As background, on March 17th, 2020, the collection and its Trichoptera holdings were closed and operations were greatly reduced. All staff and students were asked to work from home. Project PI, Dr. Ralph Holzenthal, was granted essential employee status so that he could periodically visit the collection to meet research needs. All other staff, students, and volunteers were asked to work from home, but permission was granted to a finishing graduate student to visit the collection periodically and with prior notice to access specimens for research. Holzenthal visited the collection about 2 times per week to ensure the caddisfly material was in good condition. In spite of this, material entered prior to reduced operations and during restricted access totaled 402 newly accessioned Trichoptera specimens for a collection total of 658,873 individual specimens including over 200 holotypes and representing 3,413 species, maintaining its status as one of the most important collections of Trichoptera in the world. All new accessions were entered in the collection's Specify database. Two PhD students, Luis Ernesto Rázuri-Gonzales and Lucas Marques de Camargos, completed their dissertation research in caddisfly systematics and graduated from the program. Both currently are in post-doctoral and research associate positions in Germany. Holzenthal participated in one research trip to Ecuador in March (just prior to pandemic restrictions) to continue research on caddisfly faunistics of the country with Dr. Blanca Ríos-Touma. Material was collected from 28 separate localities spanning 2 elevational gradients from ca. 4000-500 meters and represents about 2500 specimens. Specimens have all been labelled, identified to morphospecies, and are awaiting final determination to species, descriptions of new species, databasing, and accessioning into the collection. He and Dr. Ríos-Touma initiated an ancillary research project on the genomics of the fauna with Dr. Paul Frandsen, Brigham Young University, and Dr. Steffen Pauls, Senckenberg Research Institute and Natural History Museum, Germany. A subset of specimens from the March trip were preserved in 95% ethanol and set aside for DNA extraction and sequencing. This research will look at genomic data to study adaptations of Neotropical caddisflies to high Andean environments. Dr. Robin Thomson, curator of the collection, continued work on a world catalog of the microcaddisflies and on various taxonomic studies with colleagues in Ecuador, Panama, and Pennsylvania.

The taxonomic research associated with this project resulted in the description and revisions of 100s of new species of caddisflies and led to an understanding of their phylogenetic relationships and their utilization as biological indicators of water quality. In 2019, 21,378 additional specimens and 618 species were added to the collection such that the Trichoptera holdings in the University of Minnesota Insect Collection (UMSP) total 658,471 specimens, including 203 holotypes and representing 3,394 species, making it one of the most important collections of Trichoptera in the world. Specimen accessions were much higher than in previous years, because material collected in Ecuador in 2017 was identified, curated, and databased. In addition, backlogged material from Arkansas, Minnesota, New Jersey, North Carolina, Tennessee, and Wyoming, as well as Australia, Japan, and Russia was also added. Importantly, a very large and species diverse collection of voucher specimens from around the world and used in several molecular phylogenetic studies was almost completely recurated, accessioned. This was challenging as all specimens needed transfer to new, archival vials with fresh 80% ethanol. New labels were also needed. This activity resulted in the need to completely recurate all the alcohol-preserved caddisfly specimens in the collection to more efficiently use shelf and vial rack space in room 341 Hodson Hall. All of the new 2019 accessions were databased using individual specimen bar-code labels redesigned in matrix format for in-house printing, saving the collection the expense of commercial printing. The entire pinned collection of Trichoptera is housed in 21, 25-drawers specimen cabinets with sufficient expansion space allowed for future growth. The alcohol material is housed in 8, 12-shelf cabinets, with almost a full cabinet available for expansion. The Trichoptera holdings represent the taxon with the largest number of specimens in the collection. Contributions continued to a database of world Trichoptera Literature [ http://www.trichopteralit.umn.edu/ ], now containing 15,000 citations. In 2018 taxonomic and revisionary studies were continued or completed on the genera Smicridea, Ascotrichia, Chimarra from the Indian subcontinent, Atopsyche, Nectopsyche, various genera of Hydroptilidae, Cernotina, Cyrnellus, a world catalog of the family Hydroptilidae, a key to North American genera of adult and larval caddisflies, and inventories of the caddisfly fauna from Ecuador, Peru, and Panama. The project continues to participate in a large, multi-investigator project on a DNA phylogeny for the entire order Trichoptera. The project supported the research of the collection's curator (Dr. Robin E. Thomson) and one Research Associate (Dr. Roger Blahnik). Two graduate students (L.M.Camargos, PhD, L.E. Rázuri Gonzales, MS) were also supported by the project. No research collecting trips were taken in 2019, but two are planned for Ecuador in 2020.

The project continues to participate in a large, multi-investigator project on a DNA phylogeny for the entire order Trichoptera. The project hosted one researcher from Ecuador, Dr. Blanca Ríos, and two visiting PhD students from Brazil, Albane Vilarino and Everton Dias. A very large collection of voucher material received in 2017 for deposition in the collection has now been recurated, databased, and partially accessioned. The database of specimens written in the software package BIOTA was completely transferred to a new, more powerful platform using the software Specify. Sarah Schmits was contracted to complete this task.
