C. septempunctata has a broad ecological range, generally living wherever there are aphids for it to eat. [3] This includes, amongst other biotopes, meadows, fields, Pontic–Caspian steppe, parkland, gardens, Western European broadleaf forests and mixed forests.
For example, Niphanda fusca butterflies lay eggs on plants where ants tend herds of aphids. The eggs hatch as caterpillars which feed on the aphids. The ants do not defend the aphids from the caterpillars, since the caterpillars produce a pheromone which deceives the ants into treating them like ants, and carrying the caterpillars into their ...
Some caterpillars of Lycaenidae butterflies and some moths also produce honeydew. [2] In addition to various sugars, honeydew contains small amounts of amino acids, other organic compounds, and inorganic salts with its precise makeup affected by factors such as insect species, host plant species, and whether a symbiotic organism is present.

Some caterpillars even bite the female wasps that approach them. Some insects secrete poisonous compounds that kill or drive away the parasitoid. Ants that are in a symbiotic relationship with caterpillars, aphids or scale insects may protect them from attack by wasps. [18] [19] Parasitoid wasps are vulnerable to hyperparasitoid wasps.
The small, bright orange, slug-like larvae inject a toxin into aphids' leg joints to paralyze them and then suck out the aphid body contents through a hole bitten in the thorax. [3] Larvae can consume aphids much larger than themselves and may kill many more aphids than they eat when aphid populations are high. [2]
The wings are black with a horizontal yellow line across the forewings, and a diagonal yellow line across the hindwing. The underside of the wings is yellow with accents of black. A small patch of red on the ventral wing (within the small blue band) allows for distinction from the similar-looking Schaus' swallowtail. [4] Seitz -"P. cresphontes Cr.
The spiny caterpillars are striking in appearance, with black bodies and a line of eight reddish-orange dots running down the back (aposematic, warning coloration). The prolegs are dark red. The body is covered with short hairs and black spines and white dots. [2] The fully grown mourning cloak caterpillars attain two inches in length. [3]
