From time to time the eggs are collected from the cage floor and excrements and are placed in separate containers. For sorting eggs and handling small nymphs a spring-steel-tweezers has proven very useful, as you do not crush more fragile eggs. Eggs which are simply dropped or flicked to the cage floor by the adult females are at best incubated on damp peat or vermiculite. Ones which are buried by the female insects (these often possess an ovipositor for this purpose, e.g. Eurycantha, Heteropteryx, Aretaon) and deposited in the soil should be covered with a layer of substrate. Another method, which has proven sufficient for Heteropteryx and Haaniella, is to use a pencil or similar to drill small holes into the substrate each in which one egg is placed with just the operculum showing. This allows to check the eggs for fungus and mould easily. A glance should be taken from time to time in order to remove infected eggs and to avoid that egg box openhealthy eggs are affected. Some species fix or glue their eggs singly or in batcheEierschlupfdose geöffnets to the stems or leaves of the foodplants or cages (e.g. Trachythorax, Sipyloidea, Gratidia or Sceptrophasma). These are either left in the breeding cages or kept in separate containers, but should not be removed from the surface to which they are fixed, as this usually damages the egg-capsule. This also concerns to the leaf-piercing eggs of Asceles.
Different kinds of stable plastic or acrylic containers with a lid are suitable for the storage of phasmid eggs but should always have air-holes or a piece of gauze in the lid to guarantee ventilation – the eggs would become mouldy in air-tight containers. The eggs are kept at similar temperatures as the adults and nymphs and care should be ensured that the eggs do not dehydrate. Therefore it is wise to check the humidity from time to time and to slightly spray the eggs with warm (not hot!) water if the humidity appears to be too low. As for the insects, eggs should never be exposed to direct sunlight.
