BWARS forum - first, please read this

This forum is a place to discuss matters related to BWARS and general matters related to aculeates.


It is not intended as a forum for identification queries. We may add this feature in due course, but meanwhile, if you need help identifying bees, wasps and ants, please use either iSpot or the BWARS forum on Yahoo.

Production of mud by Ancistrocerus wasp

Watching Ancistrocerus wasps nest-making in my garden bee-hotel over recent years, I had assumed that they collected mud from damp areas (in a similar way to Osmia bicornis). Last year, I was able to follow a wasp from the bee-hotel to its "collecting point" and saw that it was collecting dry soil particles. This year I witnessed the same thing, with an Ancistrocerus wasp repeatedly returning to the same point. I was able to get a series of photographs from one visit showing her collecting individual soil granules (the soil was bone dry) and then flying off with a wet mud-ball.


Megachile ligniseca, records and Acer cutting

Two recent records for M. ligniseca in Mawdesley (2015) and Holmeswood ('16) - in gardens (using trap nests) of these villages in Lancashire (Half way between Chorley and Southport).

The bee last year was cutting from Norway Maple (with Sycamore also present, seemingly not used) and this years bee was likely cutting from Field Maple (no Sycamore present in the immediate vicinity).

Probably not surprising observations but not something I've read.
