COMMUNAL LARVAE

Rearing communal larvae requires special considerations because of the anount of frass produced. Often the frass is impossible to clean

  1. DO NOT keep communal species in plastic film containers after the eggs hatch
  2. SALSA JARS should only be used for temprary transportation or as a last resort
  3. Generally it is preferable to use inverted large vaccum jars for small larve and a large aquarium for mature larvae
  4. It is possible to reduce the colony size by releasing some of the larvae again but DO NOT attempt to early young colonial larvae individually or they may look for their siblings instead of eating and eventually starve
  5. Older larvae of colonial species can be kept individually or with only a few others

MORTALITY IS A FACT OF LIFE with communal species

  1. In general 10% of communal larva will raised in captivity will die before becoming adults, from disease, malnutrition and accidents
  2. Up to 10% of pupa will not emerge correctly
  3. These rates are considered normal

In order to reduce mortality

  • In order to reduce mortality keep lots of airflow to avoid excess in the frass moisture, which can cause a mold epidemc
  • Remove all larvae to a salsa jar and completely change the plants. Then place the salsa jar under the new plants a stick a leaf inside the jar. All larvae will usually climb back on to the plant within 20 minutes.

Be prepared for how much they eat (A colony Milberts Tortoise Shell larvae will eat 4-5 entire Nettle Plants in the 5th stage alone).

If possible grow the foodplant in the garden.
