I’m looking for information on the foraging range or flight distance of different species of common North American lady beetles. In particular, I need information on Harmonia axyridis, Coccinella septempunctata, Hippodamia convergens, H. parenthesis, H. variegata, and Cycloneda munda. Can anyone point me to a reference? Any information - also on singe species - is very welcome!
I’m working on gut microbes of lady beetles and found an interesting relationship between the species-specific gut bacterial richness and the body size and wonder if this might be driven by resource exploration / the foraging range of the species.
Hi Julia:
There is an excellent review made by Hodek et.al 1993 called "Long-distance flights in Coccinelidae (Coleoptera)". It reviews the information about trivial flight, migration, dormancy sites, foraging and dispersal flight distances for Harmonya axiridis, Hippodamia convergens, Coccinella septempunctata, Hippodamia convergens which are the species you are looking for. Please find attached the paper.
Regards,
Luis Miguel
Hi Julia,
there is a MSc thesis from Univ. of Hull available online, about dispersal of C. 7-punctata and H. axyridis but more in relation to invasion biology:
