Lepidoptera is one of the largest and most economically important orders of plant eating insects. Thousands of Lepidoptera are considered pests, and each year large numbers of these species are intercepted at U.S. ports of entry as larvae. LepIntercept is a comprehensive resource for identifying intercepted Lepidoptera larvae.

Just released! - Lucid Mobile Apps

A number of ITP's Lucid keys have been converted to mobile apps, allowing use of the keys in the field on Android phones and iPhones.

Anastrepha and Toxotrypana: descriptions, illustrations, and interactive keys

This system attempts to bring together in a single package all of the relevant taxonomic information for these important genera, as well as images for each species, and provides a choice of two electronic keys (Intkey or Lucid).


Antkey is designed for non-specialists, and includes over 115 ant species that are introduced, invasive, or commonly intercepted in the United States. Features include an interactive Lucid key, dynamically generated species pages, a searchable media collection of over 1,150 images, over 70 live video clips of introduced ants, a fully illustrated glossary with over 400 terms, a searchable database of introduced ant literature, and over 12,000 specimen records of introduced ants imported from Antweb.


AphID includes a key to the 66 most polyphagous and cosmopolitan aphid species. AphID also offers users detailed descriptions of morphological features critical to identifying aphids along with annotated photographs to help illustrate each feature.

Aquarium & Pond Plants of the World, Edition 2

This tool provides a comprehensive, fully illustrated means of identification for all aquatic plants currently offered for sale through the aquarium and pond plant industries worldwide and an interactive, matrix-based key enables rapid identification of over 140 genera of aquatic plants. Also included are image galleries and fact sheets for each genus, covering topics such as included species, native and adventive distributions, weed status, brief descriptions, and taxonomic information.

Citrus Resource

Citrus Resource, a commodity-based identification resource, was created to provide growers, the industry, and those associated with citrus pest and disease detection an easily accessible site to assist with their identification needs.

Cut Flower Exports of Africa

Cut Flower Exports of Africa is a tool to aid in the identification of genera of cut flowers produced in Africa and exported to major world markets. This tool includes an interactive identification key, flower images, and fact sheets. The interactive identification key runs as a Lucid3 Java applet.

Diabrotica ID

Diabrotica ID is designed to allow identification of Diabrotica species that originate from North and Central America to users lacking expertise in taxonomy of Diabrotica. Many Diabrotica species feed on flowers, leaves and roots of a wide variety of herbaceous plants, including agricultural crops, vegetables, fruits and ornamentals and are vectors of viral and other lethal plant diseases.

Dried Botanical ID

Dried botanicals are imported for varied uses including potpourri, decorative plant arrangements, and handicraft items. In the twenty-first century market, dried botanicals consist of whole or sectioned fungi, fruits, seeds, leaves, and almost anything that is botanical, has abundant air spaces ("physical fixatives" for the synthetic oils), has structural interest, and/or is inexpensive (e.g. lawn sweepings and waste products of other industries).

Federal Noxious Weed Disseminules, Edition 2

This interactive tool provides photographs, text and keys that aid in determining whether or not an unknown disseminule (e.g., seed, fruit) found as a contaminant in imported botanicals and agricultural products is a Federal Noxious Weed (FNW) and is therefore actionable.

Flat Mites of the World, Edition 2

This tool is designed to help identify any flat mite to the taxonomic level of genus, and in some cases to species, without the need for expertise in the group.


These tools have been designed for people with varying degrees of knowledge identifying rangeland grasshoppers, from the general enthusiast to the research scientist.

Hispines of the World

Hispines comprise half of the subfamily Cassidinae (sensu lato) in the family Chrysomelidae within the order Coleoptera. It currently consists of 6000 species placed in 42 tribes. The combination of the Hispinae with the Cassidinae (sensu stricto) (Staines 2002b) is historically recent. This tool uses “hispines” in the traditional sense of the genera and species in the former subfamily Hispinae to enable quick recognition. This tool contains an interactive key, an image gallery, and an illustrated guide to hispine morphology.

Invasive Mites Tool

These keys are designed to provide support to quarantine workers at three levels: training in mite anatomy and identification, preliminary identification (sorting non-actionable from potentially actionable mites), and advanced taxonomic support. The keys range in complexity from Is it a mite?, at a very basic introductory level, to species level treatments (e.g., Stratiolaelaps).


LBAM ID is designed to aid in the identification of adult or larval Lepidoptera encountered during light brown apple moth (LBAM) surveys in California. This tool includes interactive identification keys, images, diagrams, fact sheets, and a DNA sequence database.

Microlepidoptera on Solanaceae

This web site is designed to improve the ability of plant inspectors and diagnosticians to identify larval and adult Microlepidoptera that feed on plants in the family Solanaceae.

Pink Bollworm and its Look-alikes

This identification tool was created to allow users to identify the larvae and adults of the pink bollworm and distinguish them from similar species. The tool is designed for users participating in survey and monitoring programs for pink bollworm in the cotton belt of the United States.


PIAkey (Pacific Invasive Ant key) is an electronic guide designed to assist users to identify invasive ant species commonly encountered in the Pacific Island region. The guide covers four subfamilies, 20 genera and 44 species.

A Resource for Pests and Diseases of Cultivated Palms

The palm resource is a screening aid designed to support individuals involved with commodity-based surveys. It includes identification tools for cultivated palms and their pests, diseases, and disorders known to occur in the continental U.S., Hawaii, and the Caribbean Islands as of 2010, as well as those of immediate concern to these areas.

Terrestrial Mollusc Tool

Terrestrial Mollusc Tool was specifically designed to assist in the identification of adult terrestrial slugs and snails of agricultural importance. The tool also includes species of quarantine significance as well as invasive and contaminant mollusc species commonly intercepted at U.S. ports of entry.

TortAI: Tortricids of Agricultural Importance

Here you will find comprehensive resources for identifying adults and larvae of tortricids that threaten agriculture in the United States. Pest species as well as common non-target species are covered in detailed fact sheets and interactive identification keys. In addition, a DNA barcode database allows for the confirm of identifications using COI barcode data.

Scale Insects

There are four separate tools in this resource: Scale Families, Mealybugs, Soft Scales and Other Scales. Each tool contains many informational pages and images, and a Lucid interactive matrix-based identification key. The information and images can be accessed from the Lucid key or independently from it.
