Vegetation restoration in arid areas is imperative for maintaining biodiversity, but the influences of climate change must be accounted for in restoration efforts. Climate impacts often focus on the effects of temperature fluctuations, shifting water availability and plant phenological shifts, but combinations of these can result in unexpected outcomes.  Asteraceae are crucial plants to include as restoration species given their ability to sustain pollinator communities, reduce erosion, and compete well with invasives. During seed collection for revegetation on road resurfacing project at Capitol Reef National park a native florivorous fruit fly Trupanea radifera (Tephritidae) was detected on the flowerheads of Gaillardia spathulata using genetic sequencing techniques. Various species of Asteraceae were tracked across the park for both fruit fly presence and flower head infestation rate. A second fruit fly species of the genus Neaspilota was detected, and fruit fly presence was further found on six different Asteraceae species. A parasitoid (Pteromalidae) wasp was also found in the pupae of the same tephritid fruit flies.  Previous seed collection activities in the park have not detected these tephritid fruit flies. Phenological shifts and ground disturbance, caused by heavy monsoonal flows,  could be impacting tephritid occurrence rates.  There was an apparent disparity in infestation rates of tephritids on flower heads between disturbed and undisturbed sites, where disturbed sites had higher rates of fruit fly infestation on flower heads. Additionally, plants in Capitol Reef appear to be shifting back phenologically due to shifts in precipitation. Early winter months show a trend towards increasing precipitation over a period of 56 years, and the growing season has been extended later in the season. As a result, late-season blooms line up with tephritid activity in the fall, allowing them to produce two generations a year. Multiple tephritid generations a year due to plant phenological shifts may result in a reduction of Asteraceae seed production contributing to the higher infestation rates seen parkwide. However, parasitoid presence may help curb Asteraceae seed production decline. Multiple climate change induced trends bundled together can disrupt the normal oscillation of fruit fly and parasitoid cycles, resulting in lower seed production in restoration plant species. Less collectable seed material, reduced seed viability and established plants survival in disturbed areas as a result of infestation could negatively impact restoration success at Capitol Reef National Park and other arid landscapes.
