Oothecae are made up of structural proteins and tanning agents that cause the protein to harden around the eggs, providing protection and stability. [1] The production of ootheca convergently evolved across numerous insect species due to a selection for protection from parasites and other forms of predation, as the complex structure of the shell casing provides an evolutionary reproductive ...
The egg case is very smooth and lacks external fibrous material. [1] This egg case can be easily identified from all others in that it is the only one to have a steep ridge; giving the case a convex shape. [1] The keel on the egg case is considered very broad; representing 30–33% of the width of the egg case. [1]
Phereoeca uterella, known by the vernacular names plaster bagworm [a] and household casebearer [b], is a moth species in family Tineidae. [3] [1] It occurs in tropical climates, where it is common in houses, and is presumed native to the Neotropical realm. [4]
Entomological evidence collection is the process of collecting evidence based on insect clues used in criminal investigations.If evidence is not carefully preserved at a crime scene after a death, it may be difficult or impossible for an entomologist to make an accurate identification of specimens, if for example, all morphological characteristics are not preserved.
After she finds a suitable egg, an experienced female attempts to determine if the egg has previously been parasitized, using her ovipositor and antennal drumming (tapping on the egg surface). Females also use antennal drumming to determine the size and quality of the target egg, which determines the number of eggs the female will insert. [ 9 ]
The first stage of the insect life cycle is the egg, or embryo, for all developmental strategies. The egg begins as a single cell which divides and develops into the larval form before hatching. Some insects reproduce by parthenogenesis or may be haplodiploid, and produce viable eggs without fertilization. The egg stage in most insects is very ...

The number of eggs that the insect is able to make varies according to the number of ovarioles, with the rate at which eggs develop being also influenced by ovariole design. In meroistic ovaries, the eggs-to-be divide repeatedly and most of the daughter cells become helper cells for a single oocyte in the cluster. In panoistic ovaries, each egg ...
