Having a good year at a site where it is not common
No interactions present.
Do you tend to see more of these hoverflies when the weather is wet? Stubbs and Falk refer to L. glaucia occurring in lush vegetation.
I'm not sure. Certainly, I am seeing laternaria at this site much more...it's regular in one area where I never see it, usually. glaucia I rarely see there, as the site is dry heathland, really. At a nearby site in a spring-fed valley bottom, where I usually find glaucia a lot, I have not seen it yet this year! Difficult to see any patterns, really.
