Analysis of light patterns affecting the phototactic behavior of cockroaches

In general, phototactic movement allows organisms to maintain ideal advancement and physiological conditions. Not only can organisms respond to light's direction, but also to its intensity. Several defensive behaviours, especially those expressed by insects, are similarly considered as some instances of phototaxis. Photoreceptors are extremely specialized, light-sensitive cells containing photopigments that mediate phototactic responses. Cockroaches display negative phototaxis, indicating they are scared of light. Certain cockroach species undoubtedly prefer to reside in quiet, dimly lit environments, but some are similarly fond of light as humans are. At night, they'll assemble around windows or in front of TVs. Cockroaches usually escape from light because they are frightened of light.
