Examine the morphological characteristics of typical soil nematodes with the specimens in our well-populated culture.

Hypsibius sp. The water bear is a complex animal representing the unusual phylum of Tardigrades, which contains about 400 marine, terrestrial, and freshwater species.

Aeolosoma sp. A small, freshwater Oligochaete, Aeolosoma is characterized by colorful oil droplets in its body. It’s easy to culture large quantities of this microscopic organism for use in regeneration experiments: Simply add hay and wheat grains to hay medium. Culture instructions are included. Size: 2–3 mm.

Erpobdella obscura

These small marine crustaceans are supplied as adults, and measure approximately ¹/₄" in size at the time of shipment.

Cricket (Acheta domestica)or the Common House Cricket is available in adult and nymph sizes.

Cockroaches are widely used in labs for physiological, behavioral, structural, and developmental studies.

When hatched, the small, gray larvae are the traditional source for high-quality silk.

Readily Observed Strain Requires No Magnification

Long life cycle (approximately one month). Useful for comparative population studies and for preparing salivary gland chromosome squashes.

Mature Drosophila are cultured in our own labs, and are marked with the culture initiation date. Culture is shipped in our instant medium in a shatterproof vial. The pupae will usually appear within ten days of the ship date. You will also receive WARD’S Drosophila Culture Guide. Note: We can supply any of our single strains in the larger quantity for 100 students. Call our Customer Service department for details.

All of our most popular crosses, already done for you. We'll do all the pre-work, so you can spend more time with your students.

Illustrate the structure, feeding habits, responses, and reproduction of a typical Anthozoan.

These small aquatic amphibians breed readily in a freshwater tropical aquarium.

Grass frogs are low maintenance and seasonally available, typically from September to July.

This harmless insect parasitizes the Sarcophaga (flesh fly) pupae. Females usually lay 30–50 eggs in the pupae, which provide food for the Nasonia larvae when they hatch.

Four to six adults of each sex (including virgin females) have been carefully selected for the parent generation. Larvae will be visible within a week of receipt. Please order 7-10 days in advance.

We fully guarantee the purity and viability of our Drosophila melanogaster cultures. A large, vigorous culture is shipped in a shatterproof plastic vial. To ship Drosophila cultures with living larvae we require 10 days' notice prior to use date. During very cold weather, adult flies may die but eggs and larvae usually survive. Allow cultures to come to room temperature before checking under low magnification for eggs and live larvae. Complete instructions are always included.
