Have a look at Black Silverhorn Caddisfly (Mystacides nigra) | Observation | UK and Ireland | iSpot Nature. Is iSpot alone in putting (M. azurea) and (M. nigra) together? Why? FSC, for example, in the test version of their Adult Caddis Guide (Sept 2020), keep the species separate (but suggest that examination of the genitalia is required to confirm the identification.
Looking at Bug or moth? | Observation | UK and Ireland | iSpot Nature, it seems that (M. nigra) was in the dictionary at one time. Noting the expert comment on that observation from Ian Wallace, perhaps the dictionary entry should be for (Mystacides azurea/nigra)?
You might be pleased to know that I have just checked the new dictionary and there are separate entries for Mystacides azurea, Mystacides longicornis and Mystacides nigra.
Thanks, Chris. That sounds good. Any idea when the new dictionary will be live?
We’ve been working on it for a long time now. We’re expecting the latest release to be with us by the end of this month, then we’ll import it onto an evaluation server for testing before releasing both the new server architecture and new dictionary together.
[salivating with expectation]!
