Many extratropical pierine butterflies are multivoltine and have both seasonal phenotypes
and facultative diapause under photoperiodic control. Studies of univoltine-monophenic …

The phenomenon of seasonal polyphenism under photoperiodic control is now well
established in a variety of butterflies, especially members of the family Pieridae (Shapiro …

Summary 1 Phenotypic plasticity was investigated in the Tatochila sterodice species-group
of Pierine butterflies in Chile and Argentina. 2 T. s. macrodice, from the Andes of …

Two local piericl populations in western North America showing regionally aberrant
phenologies were investigated in the laboratory. Neither a partially bivoltine Pieris napi from …

We examine the hypothesis that seasonal polyphenism (response to larval photoperiod
and/or temperature) in adult wing-melanic pattern of pierine butterflies is adaptive for …

The photoperiod regime experienced by developing larvae regulates the deposition of
thermoregulatory melanin in the midwestern'segregate'of the Pierid butterfly, Nathalis iole …

The tropical butterfly, Bicyclus anynana, exhibits seasonal polyphenism. The wet season
form has large eyespots and a pale band while these characters are much less conspicuous …

The influence of photoperiod on the induction of facultative diapause was determined for a
southern Ohio population of Papilio troilus. We also investigated the extent of population …

1. Californian Pieris napi have previously been reported as producing dark‐veined and light‐
veined adults from diapausing and. non‐diapausing pupae respectively; the converse has …

Photoperiod and temperature during development were shown to control the phenotype of
adults of Catopsilia pomona pomona in a population in Queensland. These environmental …
