65: DREPANIDAE, 66: EGGARS, 68: EMPERORS,

66.007 Northern Eggar larva at 21mm found at Norland Bilberry slopes, Oct.10th 09. I over wintered it outside at this stage where it would not feed again until the following March.

66.007 Northern Eggar larva and moulted skin, Apr.13th 2010. After hibernation it began to feed up slowly on Ivy leaves. Each moult was preceded by 3 days of inactivity; it had appeared to have duplicated itself after this one.

66.007 Northern Eggar larva at 56mm long, May 29th 2010. Final instar length nearly 60mm. As it grew larger I could hear it munching the Ivy leaves from across the room and also the frass pellets as they hit the bottom of the plastic pot at regular intervals.

66.007 Northern Eggar outer cocoon, June 25th 2010. After 3 months of feeding it finally spun up ready to pupate.

66.007 Northern Eggar inner cocoon, July 20th 2010. The inner cocoon was extracted from the loosely spun outer cocoon and was over wintered again, this time as a pupa.

66.007 Northern Eggar  (male), May 22nd 2011. Finally, after caring for it for 19 months the moth emerged safely overnight. A lengthy rearing process the likes of which I'm unlikely to ever try again (hopefully...)

66.007 Northern Eggar larva at 16mm in length, swept from Heather at Norland Bilberry slopes, Mar. 22nd 2016.

66.007 Northern Eggar cocoon at Jumble Hole, Apr. 25th 2016 found by Brian Leecy. The two small holes are exits made by parasitic wasp grubs. The cocoon contained a dead larva.

66.008 Fox Moth larva feeding on Heather on Norland moor, Aug. 30th 2017. First time I've recorded this species in Calderdale.

66.008 Fox Moth, collected by day from Oxenhope moor by Chris Eastwood, Sept.18th 2016. It was given to me to rear through - not a successful venture to say the least.

66.008 Fox Moth larva as above, Sept. 23d 2016. After leaving its food alone for a day or two the reason why was soon clear - grub after grub of a parasitic wasp began emerging from the larva, 24 in all. 

The parasitic wasp Cotesia gastropachae which emerged from the Fox Moth larva above, Oct. 1st 2016.

66.008 Fox Moth and Small Elephant Hawkmoth with a Knot Grass et al in the egg tray behind. Norland moor, June 17th 2022.

66.010 Drinker larva by the towpath at Ellen Royd, Luddenden Foot on June 3rd 2022. Presumably searching for a suitable pupation site.

66.010 Drinker cocooon. Less than 24 hours later and the larva pictured above has already spun up. I only had some ferns growing in the garden to offer it but it seems to have done a good job. It's incorporated countless body hairs in to the construction.

66.010 Drinker, just 20 days after the larva above spun its cocoon this lovely male emerged. It does make you wonder how a pupa full of mothy soup can metamorphose in to such a different looking organism so rapidly.

66.010 Drinker to MV light at Hollas Lane nature reserve on July 23rd 2021. An incredible night of moth trapping with 117 species recorded and even a Gatekeeper butterfly entered the trap! An experience made all the better with fellow moth-ers Andy Cockroft and Matthew Broadbent who were present to make sure nothing went unnoticed.

68.001 Emperor Moth cocoon, Pecket Well, May 20th 08. An empty cocoon found by eagle-eyed moth-er Winston Plowes.

68.001 Emperor Moth (female), Norland moor, May 4th 05. Standing out like a beacon in a sea of Heather this remains one of my most exciting finds ever. I spent around half an hour in her company and didn't see a single admirer come to visit so I think she must have already mated and stopped releasing pheromones. Female Emperors don't feed and die shortly after egg-laying.

68.001 Emperor Moth, details as above. I was surprised to see eye spots on the underside as well.

68.001 Emperor Moth (male) at Norland moor on Apr. 30th 2022. It was attracted to one of Anthony Arak's pheromone lures, although this one was content to land a few feet away in among the Heather.

68.001 Emperor Moth details as above. It's now fully at rest allowing very close approach in the warm spring sunshine.

68.001 Emperor MothLater, on the same trip as described above, some of the pheromones from earlier must have landed on my boot and attracted this male - a surprisingly small moth, as evident when there's something to gauge their size by (photo by Anthony).

The Cromwell Bottom moth trap at emptying time in the early hours of the morning of Aug. 19th 2018. Often over run with Yellow Underwings and caddisflies (not to mention biters and wasps!) it is none the less the best way to see the fantastic hook-tips (see below).
 
65.001 Scalloped Hook-tip to MV light at the cabin, Cromwell Bottom, July 21st 2018. One of an impressive five individuals making an appearance that night. 
 
65.005 Pebble Hook-tip to MV light at the cafe area, Cromwell Bottom, June 2nd 2018. My first ever hook-tip and an exciting arrival to the light.

65.008 Peach Blossoms to light at the cafe area, Cromwell Bottom Nature Reserve, June 2nd 2018. Because of a lack of available pots these two were put in the same container - with unsurprising results! 

65.009 Buff Arches, Bankhouse wood, June 27th 2010. Netted at dusk.

65.010 Figure of Eighty to MV light at Barkisland on June 18th 2022.

65.016 Yellow Horned, one of two to MV light at Hardcastle Craggs, Mar. 15th 2014.

65.016 Yellow Horned to MV light at Norland on Apr. 14th 2022. It shows the orange rather than yellow "horns".
