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 ...
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.
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]
The Florida woods cockroach (Eurycotis floridana) is a large cockroach species which typically grows to a length of 30–40 mm (1.2–1.6 in). [2] When alarmed, adults can eject an extremely foul-smelling directional spray up to one metre (3.3 ft), [3] which inspired several of its other common names: Florida skunk roach, Florida stinkroach, skunk cockroach, skunk roach, stinking cockroach ...
On the surface, 28 ellipsoid eggs were visible, each measuring no more than 0.18 inches (4.65 millimeters) long and 0.07 inches (1.84 millimeters) wide (this is comparable to the eggs of modern ...
The micropyle is situated on top in eggs which are globular, conical, or cylindrical; in those eggs which are flattened or lenticular, the micropyle is located on the outer margin or rim. [18] [62] The eggs of Lepidoptera are usually rounded and small (1 mm) though they may be as large as 4 mm in the case of Sphingidae and Saturniidae.
Larval forms are carnivorous and may exhibit cannibalism among the individuals in a single egg case before hatching. The eggs begin to hatch an average of eight days after being laid. The egg hatches by way of the larvae eating their way out of the casing, usually by way of the lid. This process can take several days in some instances.
