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

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

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.

This activity shows Dermestid beetles assist in the breakdown of dead organic matter. Simply allow them access to the freeze-dried frog provided.
