Diagram of B. impatiens microcolony setup.
Consists of (1) Entrance/exit tube with ramp, with yellow tape placed around entry and on ramp to guide bees in; (2) Main chamber, plastic with lid on top and perforations for airflow (not pictured), with 8 individual bees; (3) Pollen balls (made in-lab with Arizona sourced pollen granules (CC Pollen High Desert brand) and 30% sucrose solution); (4) Tube with 30% sucrose solution, with small hole at base.

Flowchart of bumble bee pollination and tarnished plant bug damage trials.
Fig 3.
Tarnished plant bug pronotal width at widest point across a landscape gradient.
Red points/line are female bugs, blue are males. (A) Urban land cover, trendlines = linear regressions, shaded area = 95% confidence area. (B) Forested land cover, trendlines = linear regressions, shaded area = 95% confidence area.
Fig 4.
(A) Fruit weight in grams for flowers that were visited or not visited by a bumble bee (*** = p<0.001) (B) For all plants both pollinated and unpollinated, fruit weight in grams by presence or absence of tarnished plant bugs. Each plant was exposed to one individual for 24 hours. (p = 0.817).
Fig 5.
(A) Fruit weight by size of bumble bee visitor (p = 0.6252); (B) Fruit weight by size of tarnished plant bug the plant was exposed to for 24 hours (p = 0.0661). Both A and B only include data from fruits that were pollinated.
