Junonia coenia grisea
Photo Life History: Junonia coenia grisea
Host Plants: Plantago lanceolata; Plantago major
Suitable Lab Host Plants: Antirrhinum majus

Caring for Live Female Butterflies: Nectaring techniques
How to Find Eggs: Look on leaves.
How to Hatch Eggs: Consolidate eggs into one container.
How to Find Caterpillars in the Field: Isolated host plants. The key to finding larvae is to look in agricultural areas or other disturbed areas where the butterfly is common. Larvae can be found resting both on and off the plant. No nests.
How to Find Pupae in the Field:
Number of Broods per Year: 1-3 depending upon location.
Overwintering Stage: Adult
Avoiding Diapause Techniques:
Disease Prevention: Change out host plant and remove frass every one to two days in a closed container; every four days in an open bucket type setup.
Emergence: Emergence Container
Field Notes: Adult phenotypes can be altered significantly by exposing caterpillars to varying temperature and photoperiod; including forms rosa and nigrosuffusa. This is not to be confused with the taxon J. evarete nigrosuffusa, but rearing P. coenia larvae under short day photoperiod can produce a dark form/form rosa insect that superficially looks like nigrosuffusa.
