Webbing Clothes Moth
Pest Fact sheet No 4 Webbing clothes moth Name Common or webbing clothes moth Latin Tineola bisselliella name Size Adult 8mm-10mm long Larvae 0.5 mm – 10 mm long Identification features Adult Small moths covered with shiny whitish-gold scales. Head with a brush of orange hairs and long thin antennae. Written by David Pinniger 1 Larva White with an orange-brown head capsule. Often hidden by tubes of silk webbing. Written by David Pinniger 2 Life cycle Adult moths fly well when it is warm and females lay batches of eggs on wool, fur, feathers and other organic materials. When the larvae first hatch they are extremely small, less than 0.5 mm, and they remain in the material where they have hatched. As they feed and grow, they secrete silk webbing which sticks to the material they are living on. As they get larger, the silk forms tubes around them. They prefer dark undisturbed places and are rarely seen unless disturbed. In unheated buildings, the larvae may take nearly a year to complete their growth and each new cycle starts after they pupate and change into adults in the Spring. In heated buildings they may complete two complete cycles per year with another emergence of adult moths in the Autumn. In very warm buildings there may even be three generations per year with moths appearing at any time. Signs of damage Irregular holes, silk webbing and gritty pellets of excreta, called frass, are signs of moth attack. Silk webbing on wool carpet Written by David Pinniger 3 Silk webbing stuck to canvas fabric Materials The larvae are voracious feeders and will graze on and make damaged holes in woollen textiles, animal specimens, fur and feathers. -

Clothes Moths
Clothes Moths Integrated Pest Management in the Home The webbing clothes moth, Tineola bisselliella, (Figure 1) and casemaking clothes moth, Tinea pellionella, (Figure 2) can be fabric pests in California. They tend to hide when disturbed, so you might not notice you have an infestation until after the moths have already dam- aged your fabric, fur, or feathered items. Close examination of the objects will reveal silken webs the larvae have spun. Figure 1. Webbing clothes moth. Figure 3. Casemaking clothes moth with IDENTIFICATION its case attached. The webbing clothes moth is the most common fabric moth. The adult is gold with reddish-golden hairs on the top of its head. A row of golden hairs fringes its wings, which have a span of about 1/2 inch. Because these moths are weak flyers that aren’t attracted to lights, you’ll usually find them close to the infested items, such as in a dark area of the closet. Figure 2. Casemaking clothes moth.

True Clothes Moths (Tinea Pellionella, Et Al.)
Circular No. 36, Second Series. United States Department of Agriculture, DIVISION OF ENTOMOLOGY. THE TRUE CLOTHES MOTHS. {Tinea pellionella et al. ) The destructive work of the larvae of the small moths commonly known as clothes moths, and also as carpet moths, fur moths, etc., in woolen fabrics, fur, and similar material during the warm months of summer in the North, and in the South at any season, is an alto- gether too common experience. The preference they so often show for woolen or fur garments gives these insects a much more general interest than is perhaps true of any other household pest. The little yellowish or buff-colored moths sometimes seen flitting about rooms, attracted to lamps at night, or dislodged from infested garments or portieres, are themselves harmless enough, and in fact their mouth-parts are rudimentary, and no food whatever is taken in the winged state. The destruction occasioned by these pests is, therefore, limited entirely to the feeding or larval stage. The killing of the moths by the aggrieved housekeeper, while usually based on the wrong inference that they are actually engaged in eating her woolens, is, nevertheless, a most valuable proceeding, because it checks in so much the multiplication of the species, which is the sole duty of the adult insect. The clothes moths all belong to the group of minute Lepidoptera known as Tineina, the old Latin name for cloth worms of all sorts, and are characterized by very narrow wings fringed with long hairs. The common species of clothes moths have been associated with man from the earliest times and are thoroughly cosmopolitan. -

Natural History of Lepidoptera Associated with Bird Nests in Mid-Wales
Entomologist’s Rec. J. Var. 130 (2018) 249 NATURAL HISTORY OF LEPIDOPTERA ASSOCIATED WITH BIRD NESTS IN MID-WALES D. H. B OYES Bridge Cottage, Middletown, Welshpool, Powys, SY21 8DG. (E-mail: [email protected]) Abstract Bird nests can support diverse communities of invertebrates, including moths (Lepidoptera). However, the understanding of the natural history of these species is incomplete. For this study, 224 nests, from 16 bird species, were collected and the adult moths that emerged were recorded. The majority of nests contained moths, with 4,657 individuals of ten species recorded. Observations are made on the natural history of each species and some novel findings are reported. The absence of certain species is discussed. To gain deeper insights into the life histories of these species, it would be useful to document the feeding habits of the larvae in isolation. Keywords : Commensal, detritivore, fleas, moths, Tineidae. Introduction Bird nests represent concentrated pockets of organic resources (including dead plant matter, feathers, faeces and other detritus) and can support a diverse invertebrate fauna. A global checklist compiled by Hicks (1959; 1962; 1971) lists eighteen insect orders associated with bird nests, and a study in England identified over 120 insect species, spanning eight orders (Woodroffe, 1953). Moths are particularly frequent occupants of bird nests, but large gaps in knowledge and some misapprehensions remain. For example, Tineola bisselliella (Hummel, 1823) was widely thought to infest human habitations via bird nests, which acted as natural population reservoirs. However, it has recently been discovered that this non-native species seldom occurs in rural bird nests and can be regarded as wholly synanthropic in Europe, where it was introduced from Africa around the turn of the 19th century (Plarre & Krüger- Carstensen, 2011; Plarre, 2014). -

CORNELL COOPERATIVE EXTENSION OF ONEIDA COUNTY 121 Second Street Oriskany, NY 13424-9799 (315) 736-3394 or (315) 337-2531 FAX: (315) 736-2580 CLOTHES MOTHS INJURY: There are two species of clothes moths that commonly infest homes, the case-making clothes moth (Tineola pellionella) and the webbing clothes moth (Tineola bisselliella). It is the caterpillar (larval stage) of these insects that does the actual feeding. Clothes moths feed on all kinds of dry materials of animal origin including woolens, mohair, hair, bristles, fur and feathers. Holes are chewed in items or threadbare spots caused where fibers are chewed in carpeting. Household items that may be attacked include clothing, drapes, pillows, hair mattresses, brushes, upholstery, furs, piano felts or other natural or synthetic fabrics mixed with wool. Silken feeding tubes or hard pro- Case-making Clothes Moth tective cases are often found on infested fabrics. DESCRIPTION: The adult moths of these two species look very much alike. They are yellow- ish-tan to buff-colored with a wingspread of about ½ inch. The larvae are white with brown to black heads, and are also about ½ inch long. The case-making clothes moth larvae spin a protec- tive case out of silk and material fibers, often blending in with the fabric so damage is not noticed until a bare spot or hole is produced. The webbing clothes moth spins silk over the fibers it is feeding on but does not form a case around itself until ready to enter the pupa (resting stage). Webbing Clothes Moth Adult & Larvae LIFE HISTORY: Female clothes moths deposit soft white eggs in clothing and household furnishings. -

Modeling Hydroprene Effects on Eggs and 5 Instar Wandering Phase Larvae of the Indianmeal Moth, Plodia Interpunctella
MODELING HYDROPRENE EFFECTS ON EGGS AND 5th INSTAR WANDERING PHASE LARVAE OF THE INDIANMEAL MOTH, PLODIA INTERPUNCTELLA (LEPIDOPTERA: PYRALIDAE) by SIVAKUMAR MOHANDASS B.Sc., (Agriculture) Mahathma Phule Agriculture University, 1998 __________________________________________________________ A THESIS Submitted in partial fulfillment of the requirements for the degree MASTER OF SCIENCE Department of Entomology College of Agriculture KANSAS STATE UNIVERSITY Manhattan, Kansas 2005 ABSTRACT The control of Indianmeal moth [Plodia interpunctella (Hübner)], a commonly found serious stored product pest around the world, relies mainly upon chemical control methods. Because of recent changes in the laws and regulations governing pesticide usage in the United States, there is an increasing need for finding safer chemicals to control insect pests. Hydroprene, an insect growth regulator, is considered to be a safe alternative. In this study, I quantified the effects of hydroprene on two critical life stages of Indianmeal moth, the eggs and 5th instar wandering phase larvae. Maximum development time in the untreated controls was 13.6 ± 0.6 d at 16°C and minimum development time was 2.3 ± 0.4 d at 32°C. At 20°C and 24°C, the effect of hydroprene on egg development became more evident; development time generally increased with exposure interval, with some variability in the data. The mean egg mortality among all temperatures was 7.3 ± 4.6%. Among the treatments, mortality of eggs increased as the exposure periods increased within any given temperature, with a dramatic increase in mortality with increase in temperature. Egg mortality was lowest at 16°C when exposed for 1 h (0 ± 3%), but mortality gradually increased up to 32 ± 3% when exposed for 18 h. -
