This is a USDA-funded project in collaboration with Denver Urban Gardens (DUG) looking at insect biodiversity in urban community gardens. A very small sample of the insect individuals present across the gardens will be collected and identified. This information will give us an understanding of:
The most common community garden species
Insect pollination and natural pest control
How neighborhood characteristics impact insect communities
Insects are highly abundant, and studies have shown that the following listed forms of insect sampling have no significant impact on population sizes when done for small periods of time.

These sentinel cucumbers are being used to measure pollination services and herbivory on plants at the gardens. Cucumbers are monoecious plants requiring pollination between their male and female flowers. Using them we can see if any sites are at risk of insufficient pollination services
These traps sample flying insects. This includes bees, wasps, flies, butterflies, moths, and more. The inside of the trap is filled with water and a small amount of dish liquid to break surface tension.
These traps are good for capturing ground-dwelling arthropods such as ants, beetles, earwigs, woodlice, millipedes, springtails, etc. Note: Ours will NOT be filled with antifreeze; instead, we will use water and dish liquid.
These boxes serve as nesting sites for solitary bees, like leafcutter bees. They offer the added advantage of allowing us to identify the bee species without harming them, and the bees will remain around to pollinate the garden!

This research is supported by a USDA NIFA AFRI (Agriculture and Food Research Initiative) grant. The findings will be presented at a national conference and submitted for publication in a scientific journal. The insect specimens collected will be preserved and donated to the University of Colorado Natural History Museum's Entomology Collections, where they will be available for researchers and students for years to come.
We also aim to raise public awareness about the insect biology of urban community gardens. An informative report detailing the most common insects found in these gardens will be created and shared with members of the Denver Urban Gardens community. In addition, we will produce a short video showcasing the research process and study findings, which will be shared online.
