What ecological context can reduce a Blue Jay's incentive to risk eating SLF?
Answer
When high-fat, easily digestible native caterpillars or grubs are readily available.
The decision of a Blue Jay or a Northern Cardinal to consume a spotted lanternfly is often dictated by energetic calculus based on local food availability. If a habitat is currently rich with established, safe, and energy-dense native food sources, such as high-fat caterpillars or grubs, the bird has little energetic motivation to gamble on testing an insect whose taste might be disagreeable or whose nutritional reward is uncertain. The effort needed to consume the SLF versus the known, secure reward of native prey tips the scales strongly in favor of the familiar food option, reducing predation on the invasive species.
