Chauliodinae. Male fishfly (Chauliodinae ssp). Fishflies are members of the subfamily Chauliodinae, belonging to the megalopteran family Corydalidae. [1] They are most easily distinguished from their closest relatives, dobsonflies, by the jaws (mandibles) and antennae. In contrast to the large jaws (especially in males) of dobsonflies, fishfly ...
A bite is defined as coming from the mouthparts of the arthropod. The bite consists of both the bite wound and the saliva. The saliva of the arthropod may contain anticoagulants, as in insects and arachnids which feed from blood. Feeding bites may also contain anaesthetic, to prevent the bite from being felt.
Loa loa filariasis, (Loiasis) is a skin and eye disease caused by the nematode worm Loa loa. Humans contract this disease through the bite of a deer fly (Chrysops spp.) or mango fly, the vectors for Loa loa. The adult Loa loa filarial worm can reach from three to seven centimetres long and migrates throughout the subcutaneous tissues of humans ...
Black widow spider bites. What they look like: When a black widow spider bites, it typically causes a painful pinprick sensation. The site of the bite then swells slightly and forms a red rash ...
A fly bearing third-stage filarial larvae in its proboscis infects the human host through the bite wound. After entering the human host, the larvae mature into adults, commonly in subcutaneous tissue. Adult females measure about 40 to 70 mm in length and 0.5 mm in diameter. Males measure some 30 to 34 mm by 0.35 to 0.43 mm.
Fish that feed on mayfly nymphs that have bioaccumulated heavy metals are themselves at risk. [40] Adult female mayflies find water by detecting the polarization of reflected light. They are easily fooled by other polished surfaces which can act as traps for swarming mayflies. [10] The threat to mayflies applies also to their eggs.
Adult dobsonflies are some of the largest non-Lepidopteran insects of temperate zones such as the United States and Canada, with a wingspan of up to 18 cm (7.1 in) in some species of Corydalus. [3] The Asian Acanthacorydalis fruhstorferi can have a wingspan of up to 21.6 cm (8.5 in), making it the largest dobsonfly and the largest aquatic ...
Many species of flies of the two-winged type, Order Diptera, such as mosquitoes, horse-flies, blow-flies and warble-flies, cause direct parasitic disease to domestic animals, and transmit organisms that cause diseases. These infestations and infections cause distress to companion animals, and in livestock industry the financial costs of these ...
