a Stomoxys producing a small bubble. This process of ‘bubbling’ aids the fly in getting rid of excessive
water in the meal (nectar, dung, etc.), thus unloading the water which aids in a more efficient flight.
Blood feeding adults unload the water in a blood meal using rapid diuresis and involvement of the
Malpighian tubules. Since nectar goes to the crop in these flies we do not know how they get rid of the
water in the carbohydrate meal.

Diptera collecting in Peru

Bruce Sutton, Gary Steck (FSCA) and I are involved in a project with the Centro de Ecologia y
Biodiversidad (CIBIO), Lima concerning the taxonomy and natural history of flies (particularly
Tephritidae & Tabanidae) of Peru. Specimens were collected by Malaise traps (dry FSCA; alcohol
USNM), at metal halide/UV lights, or by hand. I am also receiving Diptera specimens from the survey
that Caroline Chaboo (Univ. of Kansas) is conducting in the Cosnipata Valley (various types of traps;
specimens are in alcohol). If you have any interest in this material, please let me know which families
or if you would want to see trap residues. The normal restrictions apply; holotypes and half of any
species are supposed to be deposited in a Peruvian institution. If you are interested in collecting in Peru
(presuming you have funding), it may be possible to add your name to our permit with sufficient lead
time (i.e., 6 months). For this year we are planning trips for June and November.
