29th: 1 Tree Sparrow behind Treshnish Old Schoolhouse. It was calling so perhaps there was another bird present. I think it was calling in our garden but I was busy photographing insects so I missed it. Tree Sparrow was until very recently, considerer a rarity in Argyll, now it is considered scarce.
1 probable Chrysotoxum arcuatum south of Ensay Burn mouth.
1 Sexton beetle poss Nicrophorus vespilloidese Treshnish wood waterfall and Dor beetle in Ensay Burn cattlegrid.
Narrow-leaved Helleborine with developing ovaries below concrete ramp on Treshnish wood farm road.
28th: 2 large dragonflies which at this time of year were most probably Golden-ringed Dragonfly in front of Treshnish Old Schoolhouse.
Re-found the bee I thought was probably Red-backed Mining Bee female in front of Treshnish Old Schoolhouse and there was at least 1 male in the same spot which was presumably the same species These are all of the female. But now I think they are Wilke’s Mining Bee. I was reading the book wrong. The wider gap in the abdomen bands points to Red-backed but these have quite a narrow gap.
I went to try and get better shots of the Wall Mason Bee but I couldn’t find it, perhaps it was too late in the day. I did find a blood bee, the small metallic furrow bee and a ruby-tailed wasp. I also found a very interesting wasp exploring the lichen on the bark of a Rowan tree but when I got back I found the mode of my macro camera had got moved onto the wrong setting! The Canon 7D mkII has a lock for exactly this reason.
It is possibly Crossocerus varus.
Leucozona lucorum at Treshnish Old Schoolhouse and on farm road to northeast of Treshnish Old Schoolhouse, Sericomyia lappona, and Sphaerophoria on farm road to northeast of Treshnish Old Schoolhouse.
27th: 1 fritillary in front of Treshnish Old Schoolhouse. At this time of year it can only be Small Pearl-bordered Fritillary (first of the year) and 1 Orange-tip in front of Treshnish Old Schoolhouse.
and 2 Picture-winged Flies Euleia heraclei at Treshnish Old Schoolhouse.
25th: Tawny Owls calling during the day time for several days sometimes several times a day but not before noon. I hear them occasionally calling in the daytime but never like this. The call is the woo-oooo call, no kwiks.
21st: 1 probable Red-backed Mining Bee in front of Treshnish Old Schoolhouse. If confirmed it is a first for Mull.
On Ensay Burn cliffs to south of the burn mouth: 1 blood bee, 1 mini-miner, 1 of the small metallic furrow bees, 1 Little Nomad Bee,
1 ruby-tailed wasp species chrysura sp. and 1 mason bee.
2 or 3 Small Heaths at Treshnish wood waterfall (first of the year), 1 Orange-tip near helleborines near Treshnish Old Schoolhouse and 3 House Martins over the lochan. Leena saw Greylags adults with gosling on the lochan. The first proof of breeding at Treshnish.
Common Blue Damselfly at Ensay Burn mouth and Large Red Damselfly on farm road to northeast of Treshnish Old Schoolhouse (both firsts of the year).
1 new Narrow-leaved helleborine at Treshnish wood waterfall.
1 Red-tailed Bumblebee at Treshnish Old Schoolhouse and 1 Four-spotted Chaser at Treshnish wood waterfall (first of the year).
1 Cheilosia illustrata at at Treshnish Old Schoolhouse (first of the year).
Narrow-leaved Hellebororine at top (and little to south) of path out of EB lower burnside path (I may have said it was Broad-leaved in previous blog post, will check)
1+ (=4) new Narrow-leaved Helleborines at new site at Ensay side of Treshnish wood and 1 Broad-leaved Helleborine and 1 Narrow-leaved Helleborine near owl-box is flowering (all the known Treshnish Narrow-leaved Hellebrorines are flowering).
Flowering Narrow-leaved Hellebororine just below top of path out of EB lower burnside path (this is where Broad-leaved Helleborine are usually found)
16th: 1 Cheilosia chrysocoma at Treshnish Old Schoolhouse. This is a Nationally Scarce species which according to the maps in Ball and Morris has been recorded on Mull before although there are no records on NBN Atlas. I have a couple of outstanding records for last year which I am still awaiting verification but this one today has been accepted.
15th: A Sparrowhawk with prey circled over Treshnish wood but then headed east (presumably to Calgary wood) where there must be a nest.
3 new Narrow-leaved Helleborines at new site at Ensay side of Treshnish wood (1 flowering) and 3 new non-flowering plants along farm road through Treshnish wood.
1 female Orange-tailed Mining Bee at Treshnish Old Schoolhouse
1 mini-miner at Treshnish wood waterfall.
and 1 probable Marsham’s Nomad Bee at Treshnish wood waterfall.
1 female Clarke’s Mining Bee still entering nest burrow at Treshnish wood waterfall
1 brief glimpse of a bee with black head and thorax and what looks like an all red abdomen. Unfortunately the two photographs are not in focus. There are no Scottish nomad bees with an all red abdomen and blood bees have a black tail.
and at the same site at least 1 larger furrow bee, at least 1 blood bee, a probable Marsham’s Nomad Bee and another which looked like Panzer’s or Fork-tailed Nomad Bee and 1 Red Wasp and 1 beetle probably Athous haemorrhoidalis.
1 Fabricius’ Nomad Bee and furrow bee at Treshnish wood waterfall.
1 Orange-tip at Treshnish wood waterfall.
1 or 2 female Orange-tailed Mining Bee at Treshnish Old Schoolhouse.
Many Chocolate Mining Bees on the Hawthorn at Treshnish Old Schoolhouse but some look different (reddish thorax and long orange hairs on inner tergites, black face and white pollen brushes on hind tibia). I sent it to an expert and he doesn’t think it is Chocolate Mining Bee but doesn’t know what it could be. I am hoping he is consulting with other experts.
1 Brachyopa and possibly Brachyopa scutellaris at Treshnish Old Schoolhouse. This time I may have got a shot of the kidney shaped spot on the inner side of the antennae which is diagnostic for scutellaris.
1 Eristalis intricaria (first of year?) and 1 Norwegian Wasp at Treshnish Old Schoolhouse.
2 Broad-leaved Hellebrones emerging below concrete ramp.
12th: Sparrowhawk flying into Treshnish wood. Broad-leaved Helleborine merging at conc ramp and all 3 plants (4 including the twin) along the farm road edge, are flowering or about to flower.
10th: 100+ geese migrating around Treshnish Point into Calgary bay.
9th: Collared Dove calling in Treshnish wood and surrounds.
8th: Bullfinch heard in Treshnish wood and Whitethroat around Treshnish Old Schoolhouse
5th: Tree Pipit, Cuckoo and Whitethroat at Loch Frisa, Sedge Warbler heard at Derevaig reedbeds (all first of year for me).
4th: Peregrine at Haunn and I heard that a Haunn guest saw one on about the 28th or 29th of last month.
2nd: 1 immature Peregrine over the Common Gull colony at Treshnish lochan. It was interesting how the gulls responded compared to a White-tailed Eagle which passed over 5 minutes before. With the eagle there was the usual noise and a couple of gulls chasing it off but with the Peregrine as well as the usual alarm calls, over 10 birds flew in perfect close formation to the north in front of the falcon with another group following it.
At Treshnish wood waterfall, at least 2 Fabricius’ Nomad Bees, at least 2 female Clarke’s Mining Bees (an another possible male), a mining bee, some furrow bees including one which is I at first thought was probably White-footed Furrow Bee, one of the 4 small metallic blue-green species but now after looking more carefully, think the head shape is not round enough. I waited 3 hours at the nest hole entrance of the latter to get shots of the whole body but it was busy burrowing with periods of rest hidden at the entrance. It never did emerge although I missed it when I moved position and caught it (or a second) entering briefly. White-footed Furrow Bee is primitively eusocial. The other similar species are Turquoise Furrow Bee, Green Furrow Bee (which is also primitively eusocial with the workers appearing in the early summer) and Smeathman’s Furrow Bee. The latter two are rare in Scotland and so far restricted to the south with 3 and 4-5 records consecutively.
I have one accepted White-footed Furrow Bee and 2 accepted Turquoise Furrow Bees from last year.
Comparing it with the head shape in Falk, I think it is probably Turquoise Furrow Bee.
I am seeing Bee Fly on every mildly sunny day.
1st: 1 Dipper at top Ensay Burn bridge waterfall. Not much in the way of bees there but many female Clarke’s Mining Bees on the willow along the burn between the that waterfall and the first bridge as well as a Norwegian Wasp and a Green Hair-streak and Wilson’s Filmy-fern.
1 Bee Fly at the north end of the Ensay hairpin bends and a Green Tiger Beetle at Ensay car-park.
2 furrow bees by the east gate to Black Park and at least 1 female Clarke’s Bee entering the nearby nest bank and what I think is my first Heath Bumblebee of the year. 1 female Orange-tailed Mining Bee at the Black Park quarry and also a fermale Clarke’s Mining Bee entering a nest broow there and another entering a nest burrow at a new site in small waterfall on a runnel up from near the west gate of Black Park at the site where last year there was a Keeled Skimmer. 1 furrow bee to east of Treshnish wood Nissen hut and a queen Common Wasp.
