Nymphs will hatch if they are in crevices in rock and will not hatch in dry conditions, whilst on sand the eggs will hatch as well. Nymphs when hatching in crevices can use the rock, bark etc. for helping hand to get out of the egg, also while on sand the nymphs can use the sand to emerge without having the egg still attached to rear legs. Cold conditions will hatch the eggs if they were in a non-dry environment, in a crevice, and on sand. Ctenomorphodes tessulatus eggs will not hatch in dry conditions. The presence of sand or litter helps the young phasmatid to completely free its metathoracic legs - if the eggs are placed loosely on the surface the nymph frequently cannot accomplish this and usually dies still attached to the shell.
