A Teratological Specimen Of Calosoma sycophanta (L.) (Coleoptera, Carabidae) From Connecticut, U.S.A
Entomological News, 2008Teratological specimens of Coleoptera are rarely observed. The anomalous morphology of such specimens presumably reduces their chances of survival, making them uncommon in the environment. A classification and suggested terminology for describing teratological specimens of Coleoptera were published by Balazuc (1948). Publications by Dallas in Argentina

Since the intentional introduction, release, and establishment of the lymantriid predator, Calosoma sycophanta (L.), in 1906–07 in the vicinity of Boston, MA, its range has continued to expand. Compilation of collection localities, all intentional releases in North America, and museum collection records permitted documentation of spread over time and a

Approximately 100 Calosoma sycophanta L. adults were released in each of 5 plots located near the leading edge of gypsy moth, Lymantria dispar (L.), expansion in Delaware, Michigan, and West Virginia. Before release, naturally occurring beetle populations were present in West Virginia, but not in the other states.

Field Observations on the Flight Activity of Calosoma sycophanta (Coleoptera: Carabidae)
Annals of the Entomological Society of America, 1971The importance of Calosoma sycophanta L., as a predator of caterpillars has been recognized for many years. The extensive outbreaks of gypsy moth, Porthetria dispar (L.), and browntail moth, Nygmia phaeorrhoea (Donovan) in New England during the early 1900's initiated concerted efforts to establish C. sycophanta in that area.

Experimental Forest Releases of Calosoma sycophanta (Coleoptera: Carabidae) Against the Gypsy Moth
Journal of Economic Entomology, 1990Releases of limited numbers of Ca/osoma sycophanta L. adults into high populations of gypsy moths, Lymantria dispar L., were made in 1988 and 1989. In 1988, 0-40 wing-clipped beetle adults were released into four plots. Larval survival of gypsy moths was least in plots receiving the most beetles, but based on gypsy moth pupal mortality and numbers of ...

AbstractIn feeding choice tests, first- and second-instar larvae of Calosoma sycophanta L. preferred gypsy moth, Lymantria dispar (L.) (Lepidoptera: Lymantriidae), pupae as prey but third-instar larvae most often consumed caterpillars. All beetle larvae preferred female pupae over male pupae.

Calosoma sycophanta L.(Col., Carabid.) andNabis apterus F.(Hemipt., Nabid.) were observed attacking and feeding onLymantria monacha, Bupalus piniarus andDiprion spec.-larvae and pupae in some pine stands in southern and northern Bavaria 1965. It is intended to investigate the two species in regard to their biology and importance for biological control ...

A newly-developed larval diet for Calosoma sycophanta L. consists of beef liver and chicken meat. Larvae reared individually on this diet develop at about the same rate and have the same survival as those fed gypsy moth pupae, Lymantria dispar L., the usual prey of the beetle. However, adults of diet-reared larvae were significantly smaller than adults

Emigration and spatial dispersion of the gypsy moth predator Calosoma sycophanta
Entomologia Experimentalis et Applicata, 1987AbstractMark‐release studies of Calosoma sycophanta L. (Carabidae) in two 40000 m2 areas were done using traps deployed in 10 by 10 grids. In both areas, gypsy moths, Lymantria dispar L. (Lymantriidae), were abundant the first but not the second year of sampling.
