When butterflies emerge from the pupa, the butterfly will pump a fluid called meconium. This liquid is stored in the intestine of the butterfly. When the butterfly has completed pumping the liquid into its wings, the excess is expelled. The red liquid is a natural occurrence and is part of the butterflies hatching process. 

This is normal and happens when the pupa is trying to ward off any predators or intruders that are near them. The wiggling and shaking does not harm them.

No, it is not recommended to do so. As opening the cups may introduce the sterile cups to bacteria and if hand handled the oil and salts could harm your caterpillars. We only recommend opening the cups to clean the caterpillars frass. Once they fully pupate and form the chrysalides to transfer them into the butterfly habitat.

No, the artificial diet will dry out resulting in the food not being edible. Keeping the caterpillars in their cups protects them from bacteria. If by any chance one caterpillar is sick and they are all one one cup, it will spread to the others. For the highest success rate we have placed the caterpillars in individual cups.

The entire process from egg to caterpillars takes about 4 weeks. When you receive your kit the painted lady caterpillars take about 2 weeks to reach the butterfly stage. The pupae take about 5 to 8 days to hatch.

The painted lady caterpillar goes through 5 instars. Each instar it goes through the caterpillar will shed its skin. The black balls that are found in the cups are the shed skin of the caterpillar.

When the butterflies emerge and have completed pumping meconium into their wings, the excess is pumped out their abdomen. The red liquid will drip on the side and bottom of the cage. Placing a paper towel will ensure the space will not get stained with the liquid.

We recommend releasing the butterflies within 2 to 3 days after they have emerged weather permitting.

Using the brush provided in your kit, Remove the frass (yellow/brown balls) , their black shed skin and webbing in the cups every 2 to 3 days as necessary. Please see the painted lady kit instructions that go over this step in detail.
