One Culture from Each of the Four Major Types

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.

Anodonta subobicularis.

Enchytraeus sp. Culturing this terrestrial Oligochaete quickly produces a large population for general study or a source of food for fish and amphibians. Culture instructions are included.

Useful in regeneration studies, these freshwater Oligochaetes are easy to handle and to culture.

Erpobdella obscura

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

The marine hermit crab is a scavenger and preys on small animals.

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

This species of termite is very large, and you can easily observe the distinct differences of the several roles that exist in their eusocial colonies.

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.

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.
