The rear section of a butterfly (or other insect) which contains the internal organs like digestive
system, excretory system, nervous system and sexual organs. On a larvae
it is segments 4 to 11.
Scales on some male butterflies that emit a scent (scent scales or sex gland).
Appendages for sensing which occur in pairs on the head of the
imago butterfly (or other insect).
Separated into two equal parts.
A silk tent spun around the larva before pupation.
The few New Zealand Butterflies that do this usually use silk to hold some dead leaves in place
The hind part of a pupa by which some species hang during
A state of hibernation which is triggered by changes in temperature and day-light, this enables
the butterfly to survive winter. Often mixed up with quiescence.
A Butterfly (or other insect) that has two or more different forms, generally, but not limited to,
a male and female form.
An insect that is active in the daytime, eg, a day-flying Moth.
A line along the top of the larva.
An antenna-like elongated flexible unsegmented extension on the body,
usually on larvae.
A plant or plants that the larvae feed on.
The larvae's droppings.
A silken strand that us used to hold the pupa in place against a twig, wall,
The front section of a butterfly (or other insect) which contains the eyes,
antennae and proboscis.
On the larvae the head contains the mandibles,
eyes and sometimes setae.
The forth and last lifestage of a Butterfly. This is the flying stage
that really grabs our attention.
The period of a larva's life between moults of it's
skin. Most butterflies have 5 instars. The final instar is sometimes referred to as the
pupa (6th instar).
The second lifestage of a Butterfly where it begins to grow. This is the
second most noticeable stage as larvae of most butterflies are fairly obvious on their
foodplant. Larvae are split into 11 segments
behind the head.
The side of the Butterfly. Usually it refers to a line down the side of the
Butterflies have 4 lifestages starting with the ovum, then the
larva, then the pupa and finally the
imago. The change between each lifestage is called
Extending along the long axis of the body, from the head to the tail.
The mouthparts of the larvae (or other insect).
The middle of the thorax that contains the second pair of legs and first
pair of wings. On a larvae, it is segment 2.
When a Butterfly (or any insect) has a change in lifestage and changes
from a ova to a larva, larva to a
pupa or pupa to a imago.
The rear of the thorax that contains the third pair of legs and second
pair of wings. On a larvae, it is segment 3.
When a larva sheds it's skin to grow. The final moult is when a
larva turns into a pupae.
An insect that is active in the nighttime, eg, a Moth.
An eyelike spot found on many species of butterfly.
Egg-laying (oviposited - a laid egg).
The first lifestage of a Butterfly (or any insect).
The Butterflies tongue or feeding tube.
Prolegs (False Legs)
The middle and hind legs of a larvae. These disappear when the butterfly
pupates into a imago.
The front of the thorax that contains the first pair of legs. On a
larvae, it is segment 1.
Pupa or Pupae (Chrysalis)
The third lifestage of a Butterfly where it changes from a
larva to a imago. This stage is well hidden to avoid
predators and the worst of the weather. Different species of Butterflies use different methods
for pupae placement.
1. The act of changing from a larva into a pupa.
2. The period of time spent in the pupa stage.
A state of slowing all activity in cold weather. A state most of our native Butterflies use during
the winter months, hence the occasional activity and sightings on a warm winter's day. Generally
referred to as hibernation. Often mixed up with diapause.
1 of the 11 divisions of a larvae's body. The segments are counted from
the head, so number 1 is the one first one behind the
head, number 2 is the next one and so on until number 11 at the tail end.
Each segment may contain one pair of legs, 1 pair of prolegs and a pair
A stiff hair or bristle-like part of the body. Usually found on larvae of
the family Nymphalinae.
The holes a Butterfly breathes through. They are found on the side of the
abdomen of larvae, pupae and
The middle section of a butterfly (or other insect) which contains the wings and legs. On a
larvae it is segments 1 to 3.
The 'belly' of a butterfly or larvae. The lower part of the
