Funded Project
Funding Program: IPM Partnership Grants
Project Title: Identification Guide to Crane Fly (Insecta: Diptera: Tipulidae) Pests of Turfgrass in the Eastern U.S.
Project Director (PD):
Jon Gelhaus [1]
Lead State: PA

Lead Organization: Academy of Natural Sciences of Philadelphia
Undesignated Funding: $7,560
Start Date: Jun-01-2007

End Date: Mar-31-2008
Pests Involved: crane flies, fly, craneflies, cranefly
Site/Commodity: turfgrasses, lawns, community, residential
Area of Emphasis: invasive species
Summary: An ease of use identification guide is needed at this time by extension agents, turf grass care specialists and homeowners to separate the species of crane flies likely to be found associated with turf grasses, and focusing on the species implicated in causing turf grass damage.

Objectives: This project will involve developing taxonomic characters for distinguishing the adult, pupal and larval stages of pest and non-pest crane flies in turf situations, and developing these characters into an on-line interactive identification aid (key). Through field experience, interactions and identifications of samples from extensions agents and homeowners, and a search of the literature, I have selected the 20 species most likely to be found in association with turf, including both introduced and native pest species. Specimens for all these species, and their associated larval stages, have been assembled for study in the collections of The Academy of Natural Sciences.

The species will be compared for nearly 50 morphological distinctions between them, in both adult and larval stage (not all are known as larvae), which are useful in terms of an identification guide. These distinctive features will be photographed using a state of the art digital imaging system at the Academy of Natural Sciences. The character set, and the images documenting the set, will be input into software developed by DiscoverLife for developing on-line, interactive identification keys.
