About the Moth Studies at 9601 Oak Pass Road
All of the moths listed/figured under the “BACK PORCH....” heading (except for a few diurnal spp.) were attracted to lights at night, using one or two 150-watt incandescent “blue-daylight” bulbs, up until June of 1956, when two 15-watt ultraviolet (uv.) or “black lights” (G.E. F15T8/BL) were obtained and used exclusively thereafter. The lights were suspended in front of a dull white sheet, which was tacked onto a wooden wall, on a deck at the far NE. corner of the house, overlooking an east-facing slope at the edge of the ridge, which dropped off steeply just below the deck (see A-series habitat photos). The deck wrapped around the eastern and northernmost ends of the building, and was about eight feet above the ground at the point where the collecting-site was located. This gave a wide arc of illumination, out over the diverse and undisturbed native flora growing everywhere on this ridge a rich blend of Chaparral/Southern Oak Woodland/Coastal Sage Scrub (after Munz 1974). IT WAS A SUPERB LOCATION! Habitat Photos in section 1C show color photos of the home location, and other nearby habitats.
The lights were frequently operated all night (on “good” nights), as it was easy to check them at any time, simply by stepping out onto the deck. No traps were ever used. The “early morning accumulation” on the wall often revealed species that rarely (if ever) appeared much before midnight. The arctiid, Grammia hewletti, was a good example of the latter arriving almost strictly between 2:00 to 4:00 A.M.; and this was further restricted to a narrow, 2-week “window”, which only extended from about the last week of April into the first week of May! As there was an ample roof-overhang above the deck, moths resting all night on the wall never got wet during rain or drizzle. I was usually able to spread everything fresh the same night, or within a day or two. Green (or green-marked) species such as Nemoria leptalea (shown at right) were usually frozen, if the green was unstable and thus inclined to discolor in the ethyl acetate killing jars.
Nocturnal searching for larvae in the surrounding habitat was a frequent (and often rewarding) pursuit. From early childhood, caterpillar hunting and rearing had always been a special interest (and still is)! It was through this activity that I came to know the habits of many strictly nocturnal larvae, such as Behrensia conchiformis (MONA 10178a), Pleromelloida cinerea (MONA 10031), and Zenophleps lignicolorata (MONA 7406), etc., etc., etc.. Unfortunately, during the earliest years, I only reared larvae purely for the fun of learning what would emerge, but never kept any notes (or specimens) for documentation! Living ova (eggs) were often obtained from confined females. Sometimes these were shared with Dr. John A. Comstock (then of 1373 Crest Rd., Del Mar), or with Frank Sala (then of Burbank), during the mid to late 1950's. A few of these life histories were illustrated by Comstock's watercolor paintings. [Click here for some published examples.]
See also Buckett (1964), regarding the taxonomy and life history of B. conchiformis, the preserved early stages of which were supplied to him from additional rearings that I later undertook in a forest habitat west of Corvallis, Oregon (1962-63); this life history was catalogued under N.43 in the McFarland larval collection (L.A. County Museum). This life history was reported as “unknown” in a recent Oregon publication!! (Unknown to some, perhaps....). [Click here for a condensed version of the Oregon studies (McF. 1963), with specific emphasis on the included life history observations, and other (supposedly) “unknown” details that were recorded during this intensive study, that was carried out 45 years ago....] It may indeed have been a long time ago, but that doesn't alter any of the observations that were reported in the 1963 publication (on file in the O.S.U. Dept. of Entomology) ....
