Gartside.(c) K Gartside Found at a high altitude, possibly 900ft asl One of only 3 records from the region but widespread in Southern England. Associated with flowers, mainly clover where the larvae probably develop in the seeds (Hodge, 1997) Adults emerge from hibernation in April and a new generation appears by July Cassida vibex (Chrysomelidae), Ainsdale, VC59, 20/4, P. Kinsella. (c) P.Kinsella Range is expanding North. This the most northerly record within the Tanyptera region.

Seemingly a new species to the North West A wetland species associated with sides of rivers or ponds The larvae feed within galls formed in the seed-capsules of Veronica species Phyllotreta striolata (Chrysomelidae), Gowy Meadows Nature Reserve, VC58, 22/4, C. Washington.Another apparent new species to the North West A scarce beetle with very few UK records Hosts include wild and cultivated Brassica. spp Large hind legs allow the beetle to jump, hence the name “Striped flea beetle” Collembola (Springtails) Diplopoda (Millipedes) Diptera (Flies) Cheilosia nebulosa (Syrphidae), Ainsdale NNR, VC59, 15/4, P.

(c) P.Kinsella A possible first sighting on the Sefton coast Within the region has also been found in Oldham area and North Lancs Tends to visit flowers Crataegus, Prunus, Salix, Taraxacum and Tussilago Records of the species are very scattered in the UK Eriozona syrphoides a (Syrphidae), Ravenmeols LNR, Formby, VC59, 25/4, P. Kinsella . (c) P.Kinsella Another possible first sighting on the Sefton coast Was recorded on sycamore, however species is associated with pine Could be an unknown population in local coastal pine or a vagrant from upland area The larva is aphidophagous and reliant on aphids found on mature conifers (Abies , Picea ) Hemiptera (True Bugs) Hymenoptera (Bees, Wasps & Ants) Bees Andrena labiata (Andrenidae), New Ferry Butterfly Park, VC58, 15/4, R. Lowry (c) R.Lowry Recorded from a male specimen ID confirmed during Tanyptera Project mining bee ID workshop Few records in the North West so far Localised to coastal areas it is found throughout southern England to north Yorkshire and Wales. Possibly increasing in numbers. Wasps Sawflies Aglaostigma fulvipes (Tenthredinidae), Sands Lake, Ainsdale, VC59, 17/4, P. Kinsella. (c) P.Kinsella A possible first sighting on the Sefton coast Has been observed in south Liverpool previously Larvae feed on bedstraws (Galium spp .) Females cut the stem partially through just above the egg laying site.
