Caterpillar Setups

Open Terrarium technique for indra swallowtails

This photo shows indra swallowtails on bouquets of parsley (Cymopterus terebinthinus) feeding in an open terrarium. It's important that these terrariums have a screen lid; so that caterpillar frass can dry. It's also critical to replace hostplant cuttings every 2-7 days depending upon the variety of your parsley. My paper on Papilio indra goes into much more detail on the finding and caring for their larvae.

Closer photo still of hostplant cuttings of Cymopterus terebinthinus placed in water bottles for the open terrarium technique.

Open Terrarium Colias meadi

Here is Nicky Davis' setup for raising caterpillars of the mead's sulfur (Colias meadi.) Notice that she has the larvae exposed to 24 hours of light to help coax the larvae to go through to pupae without diapausing as half-grown larvae. Nicky (with the coaching of Jack Harry) did very well with these larvae.

Double Decker Open Terrarium

Some caterpillars feed on very tall host. Here is a photo of two terrariums fastened together. One could also simply buy a 20 gallon terrarium to get the same effect. This setup has caterpillars of the southwestern orangetip (Anthocharis thoosa thoosa.)

Open Terrarium with Base

This is an interesting derivative of the Open Terrarium technique. Because last instar indra swallowtail caterpillars can wander off the plant to rest, this setup makes it much easier for them to return to the plant to feed.

There are holes drilled in the base of this setup where the neck of the water bottles enter allowing for the stalks of the host to be right at the bottom of the cage allowing for easy exit and return for wary indra caterpillars.

Potted Plant/Open Terrarium Combo method

Here is a potted plant of fennel (Foeniculum vulgare) which serves as a great lab host of many machaon group swallowtails. The potted plants are in an open terrarium; but, to keep the plant and caterpillars from cooking, I have placed a screen top to allow for airflow. In this photo, the larvae feeding on the fennel are desert swallowtails (Papilio coloro.)
