Adult Empid phenology

Made up of 24 tesselleta and 66 livida I don't claim this is much of a sample.  Can't say my sampling method is anything more than casual either.  Still, the almost complete absence of any overlap in the dates when I have come across these two species in South Bedfordshire in recent years seems quite striking?

Re: Adult Empid phenology

That's a nice illustration of flight times for two spring and summer species. As you say the tiny overlap is very surprising. We should all look at our data now and see what patterns emerge from other areas.
