Filming VarWild: Carcharodus alceae

Life cycle of butterflies in Provence


Ichneumonidae : Carcharodus alceae parasitized by Hyposoter ebeninus

The parasitoid Hyposoter ebeninus (Gravenhorst, 1829) (Hymenpotera: Ichneumonoidea) can parasitize the caterpillars of different butterfly species from the familie Pieridae (Pieris brassicae, Euchloe crameri) and Carcharodus alceae. Only one egg is laid inside the body of the caterpillar. Before hatching the parasitoid larva mummifies the body and will become a pupa inside.

Braconidae : Carcharodus alceae parasitized by Cotesia glabarata

The parasitoid wasp Cotesia glabrata (Telenga, 1955) (Hymenpotera: Ichneumonoidea) is a well known of Carcharodus alceae and C. tripolina. The female of Cotesia glabrata can lay up to 40 eggs in one caterpillar.

Eulophidae : Carcharodus alceae parasitized by Elasmus viridiceps

The parasitoid wasp Elsmus viridiceps (Thomson, 1878) of 2-3 mm in size (Hymenpotera: Chalcidoidea), parasitizes the young caterpillars (instar 1 or 2) of The Mallow Skipper (Carcharodus alceae Esper, 1780). The larvae of Elasmus viridiceps develops outside body of the caterpillar (ectoparasitoid), and prevents further development of its host (idiobiont). Depending of the size of the caterpillar one or two eggs are layed on the caterpillar. After three to four days the larva becomes a dark brown pupa, from which after two days an adult emerge. The parasitized Mallow Skipper caterpillars were found on Common Hollyhock (Alcea rosea).
Elasmus viridiceps is polyphagous and is well-known from a large number of different Lepidoptera hosts: Coleophora caespititiella, C. fuscedinella (Coleophoridae); Exoteleia dodecella (Gelechiidae); Caloptilia stigmatella (Gracillariidae); Earias chlorana (Noctuidae); Adoxophyes orana, Pandemis heparana, Rhopobota naevana, Sparganothis pilleriana (Tortricidae) [Universal Chalcidoidea Database]

Tachinidae : Carcharodus alceae parasitized by Thecocarcelia trichops

Thecocarcelia trichops (Herting, 1967) (Diptera) is a rare tachinid, only known from the genus Carchrodus. Little is known about the biology of this parasitoid. In September 2012 a puparium was reared from a chrysalis of the Mallow Skipper (Carcharodus alceae), on 28 September an female tachinid emerged. In 2013 and 2014 more T. trichos adults where reared from Mallow Skipper chrysalises, and on two different occasions a female was observed parasitizing small caterpillars by inserting its telescopic ovipositor into the shelter of the caterpillar.
