Meeting Abstract 76-1  Monday, Jan. 6 08:00 – 08:15  Cockroaches bend head and use legs differentially to traverse grass-like beam obstacles WANG, Y*; OTHAYOTH, R; LI, C; Johns Hopkins University ywang460@jhu.edu https://li.me.jhu.edu/ Cockroaches are excellent at traversing dense obstacles in complex terrain. For example, to traverse grass-like beam obstacles, the discoid cockroach often transitions from a pitch […]

HENRY, J.D.*; O’CARROLL, D.C.: What visual information do hawking dragonfly predators use to intercept prey? Dragonflies are voracious predators that locate and intercept prey with astonishing accuracy. Many dragonflies (e.g. Corduliidae and Aeshnidae) are hawking predators, hunting while patrolling a territory. Dragonfly hunting is a visually guided behavior, utilizing large, highly acute eyes. Hawking dragonflies […]

THEOBALD, J.C.; WARRANT, E.J.; O’CARROLL, D.: Sphingid moths have evolved visual neural filtering adapted to the light levels of their active states The sphingid moths comprise diurnal, crepuscular, and nocturnal species which fly with remarkable agility: quickly between flowers and hovering while feeding. Despite the drastic differences in luminance during these similar behaviors, sphingids share […]

FRYE, M.A.*; DICKINSON, M.H.: Fusion of visual and olfactory signals for flight control in flies Fruit flies exhibit remarkable capacity for locating desirable odor sources within variable and complex visual environments. Using a combination of real-time 3-D video tracking during free flight, and a visual ‘virtual reality’ flight simulator modified to deliver odor during tethered […]

FEUERBACHER, ERICA N*; DICKINSON, MICHAEL H: Effects of ambient light level on free-flight behavior of Drosophila melanogaster. Natural populations of organisms experience several orders of magnitude differences in ambient light level through the course of the day. Both spatial and temporal visual resolution depend on light level, suggesting that light level and organisms? ability to […]

TAMMERO, Lance; DICKINSON, Michael: A characterization of the response to visually simulated object approach in Drosophila As a fly approaches an object, image expansion occurring across the fly’s retina and a fly is faced with the choice of either avoiding the object or landing on it. To quantify the dynamics of the fly’s response to […]

POLIHRONAKIS, Maxi; University of Connecticut: Why are some genitalia asymmetrical? The fraterna species complex (Coleoptera: Scarabaeidae: Phyllophaga) is currently comprised of approximately 30 taxa with distinct asymmetrical male genitalia as well as species-specific female genitalia. The most striking asymmetry arises between the two parameres located on the posterior portion of the male genitalic capsule. It […]
