How long does it take for a verbasci to pupate?
A. verbasci has a life cycle ranging from 1–3 years, depending upon the environmental conditions. A study in 1958 found that temperature is able to affect larval development, concluding that the periods of incubation and pupation of A. verbasci decrease with increase of temperature (the life cycle is thus quickened with a moderate rise in temperature). Incubation decreased from 54 days at 15 °C to 12 days at 30 °C, and the pupation decreased from 89 days at 10 °C to 9 days at 25 °C. Relative humidity was shown to have little effect.
What is the predator of A. verbasci?
Among the natural predators of A. verbasci, one of the most well-studied is the parasitoid wasp Laelius pedatus (in the family Bethylidae ). Upon discovering an A. verbasci larva, a female wasp will land on the larva's dorsal side and attempt to line up its long, stinger-like ovipositor for a paralyzing blow to the thorax. In response, the larva will erect long hairs on their abdomen and attempt to brush these hairs against the encroaching wasp. The hairs detach and stick to the wasp on contact, presumably causing some sort of irritation. Evidently, such irritation is not enough to deter an attack on A. verbasci larvae, as the vast majority of attacks are successful. By comparison, the closely related beetle species Anthrenus flavipes – which has slightly longer hairs than A. verbasci – uses such a defense more effectively.

Habitat & Hosts
Carpet beetles adults can be found outdoors on crape myrtles or other plants where the adults eat pollen and nectar. When adult carpet beetles are found indoors, it is often near doors and windows where they are attracted by sunlight. Adults may also be found in rodent or bird nests.
Life Cycle
Eggs (50-100) are laid by adult females near food sources. Larvae hatch out after about two weeks and begin to feed. There can be from 6-12 instars (larval stages) and it can take two to six months before pupation occurs. Adults emerge from the pupae after about 1-2 weeks.

Overview
Interaction with humans
The larvae of A. verbasci are a common household pest. Adult beetles usually lay their eggs in air ducts, in closets, under furniture, or under baseboards. Once hatched and until they pupate into adults, the larvae hide in dark, undisturbed areas and feed on organic material. The larvae are thus responsible for the damage of various items, such as furniture, clothing, blankets, furs, and carpet…
Description
Adult A. verbasci range in length from 1.7 to 3.5 mm (0.07 to 0.14 in). The body is rounded, almost spherical. The elytra and pronotum are covered in fine scales of different colours, creating an irregular pattern of white, brownish and yellowish patches on these features. The white scales are focussed along the lateral margins of the pronotum and on the elytra, where they form three bright, wavy …
Distribution and habitat
This species is present in most of Europe, in the eastern Palearctic realm, in the Near East, in the Nearctic realm, in North Africa and in North Asia, also in the Neotropics.
Diet and behaviour
Larvae feed on keratin and chitin of natural fibers (dead insects, animal hair and feathers) throughout their development, eventually experiencing a dormancy period (also known as diapause) prior to pupation into the adult stage. The length of the dormancy appears to depend on environmental factors, with the most likely zeitgeber, or trigger, being photoperiod. Adults feed on the pollen and nectar of flowering plants.
