Abstract (part):
Non-prey foods are an integral component of the diets of most predaceous coccinellids. Under field conditions, numerous coccinellids consume nectar, honeydew, pollen, fruit, vegetation, and fungus. These non-prey foods are used by coccinellids to increase survival when prey is scarce, reduce mortality during diapause, fuel migration, and enhance reproductive capacity.

Ecology and behaviour of the ladybird beetles (Coccinellidae). By Hodek, I., H.F. van Emden & A. Honěk (eds).

from publisher's website:
Ladybirds are probably the best known predators of aphids and coccids in the world, though this greatly underestimates the diversity of their biology. Maximising their impact on their prey is an important element in modern conservation biological control of indigenous natural enemies in contrast to the classical approach of releasing alien species.

Abstract.—We searched for and collected data on a phenomenon known as ladybug washups, in which large numbers of coccinellids aggregate on the shores of major bodies of water. Our field season lasted from 5/23/2008 until 8/12/2008 in the Finger Lakes Region of New York, United States.

Aggregation of lady beetles on the shores of lakes (Coleoptera: Coccinellidae). By Lee, R.E., Jr.

Lee, R.E., Jr. 1980. Aggregation of lady beetles on the shores of lakes (Coleoptera: Coccinellidae). American Midland Naturalist, 104(2): 295-304.
ABSTRACT: Aggregations of lady beetles, predominately Hippodamia convergens and H. tredecimpunctata, were commonly observed on the shores of lakes in the Upper Midwest during the autumn and spring. The beetles remain on the shore for only a short time, usually dispersing within 2-3 weeks. Lady beetles from autumn shore aggregations and overwintering aggregations are characterized by the presence of large amounts of fat, reproductive inactivitiy, empty digestive tracts, a skew in the sex ratio favoring females and the behavioral tendency to form aggregations.

ABSTRACT:
A taxonomic study of the Coccinellidae of Louisiana was undertaken in 1965 to identify the species occurring in the state. Keys and descriptions are provided for the 6 subfamilies, 11 tribes, 27 genera, and 71 species recorded as occurring in the state. Of the species listed, 38 are reported as new. Distribution records by parish and dates of seasonal occurrences are given.

"The following is a list of Coccinellids collected principally by the writer in the vicinity of College Station and in Hidalgo county, Texas, during 1930, 1931, and 1932. Notes, as far as possible, are given on the habitat, host, and the date that each species was collected. Of the 64 species and varieties listed herein, 19 have not been heretofore reported from this state. The writer is indebted to Dr. E. A. Chapin for determining some of the species of Hyperaspis and Scymnus."

Survey of lady beetles (Coleoptera: Coccinellidae) found on Texas high plains cotton, alfalfa and weeds. By Carroll, S.C., M.N. Parajulee, and M.D. Arnold.
Proceedings of the World Cotton Conference (September 10–14, 2007), Lubbock, TX., 2007
Full PDF - Manuscript
A study was conducted during the February to November periods of 2004 and 2005 to determine the seasonal presence and reproduction of lady beetle species on cotton, alfalfa, plus over 20 prevalent Texas High Plains weed species. Over the 2-year study period, a total of 221,209 plant sweeps yielded 27,058 lady beetle adults and 3,936 larvae.
The adult specimens represented a total of six different species with the convergent lady beetle, Hippodamia convergens Guerin-Meneville, easily representing over 80% of the overall population.
