"weather"

Conifers come in all shapes and sizes — and so do their cones.
Includes: 6 pine cones, 6 spruce cones and 6 cedar cones.
*Pine cone factoid: Pine cones can forecast the weather! In dry weather, the scales dry up and open out. If they start to close up, wet weather is coming!

Drosophila melanogaster, the common fruit fly, is widely used in genetic studies. They express a number of mutations such as eye, wing, and body mutations. Students can study sex-linked, recessive, and dominant mutations. Drosophila also makes an excellent live food for mantises, small reptiles, and amphibians. Drosophila demonstrates complete metamorphosis with egg, larva, pupa, and adult stages in its life cycle.

Erpobdella obscura

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.

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.

The set Includes cultures of wild, white, brown, dumpy, vestigial, vestigial brown and sepia.
