Monarch and Swallowtail caterpillars, like the butterflies, are never confused by people who see them often, but easily confused by people who read descriptions of them. [179], Although monarch caterpillars will feed on butterfly weed (Asclepias tuberosa) in butterfly gardens, the plant has rough leaves and is typically not a heavily used host plant. 5 out of 5 stars. The upper side of the female is more of an orange-brown with wider black borders than the male. [139][140] The bacterium Pseudomonas aeruginosa has no invasive powers, but causes secondary infections in weakened insects. Seeing a Monarch butterfly is a sign from your guardian angels. [79] The combination of filtered and unfiltered green opsins permits the butterflies to distinguish yellow from orange colors. Many of the priority projects that the national strategy identifies will focus on the I-35 corridor extending for 1,500 miles (2,400 km) from Texas to Minnesota that provides spring and summer breeding habitats in the monarch's key migration corridor. At this point, it is about 2.5 cm (1") long and 10–12 mm (3/8–7/16") wide, weighing about 1.2 grams. Females can mate, and lay eggs, several times. [165], Climate variations during the fall and summer affect butterfly reproduction. This happened even with monarchs that were brought into captivity from the wild for a few days. [123][124][125] More recently, the genetic basis of monarch migration and warning coloration has been described. On one hand there are many positive aspects of captive rearing. The overwintered population of those east of the Rockies may reach as far north as Texas and Oklahoma during the spring migration. The eggs weigh less than 0.5 mg each and have raised ridges that form longitudinally from the point to apex to the base.

The fifth instar larva has a more complex banding pattern and white dots on the prolegs, with front legs that are small and very close to the head. [78], Physiological experiments suggest that monarch butterflies view the world through a tetrachromatic system. However, the migrating generation does not reach maturity until overwintering is complete. [137] A 2016 study also attributed the last decade's ten-fold decline in overwintering numbers of the eastern monarch population to the loss of breeding habitat, namely the many species of milkweed (Asclepias species) that developing larvae require for food; however, scientists believe there are other factors as well. Some individuals have taken this practice to the extreme, with massive operations that rear thousands of monarchs at once, like one in Linn County, Iowa. Conservationists are lobbying transportation departments and utilities to reduce their use of herbicides and specifically encourage milkweed to grow along roadways and power lines. Males tended to have larger wings than females, and were heavier than females, on average. Once the caterpillar grows, it is important they have space to pupate. Some predators can differentiate between these parts and consume the most palatable ones. [46] While breeding, monarch habitats can be found in agricultural fields, pasture land, prairie remnants, urban and suburban residential areas, gardens, trees, and roadsides – anywhere where there is access to larval host plants.[47]. The Buckeye Butterfly. Female monarchs tended to have thicker wings, which is thought to convey greater tensile strength. Along with sperm, the spermatophore provides a female with nutrition, which aids her in egg laying. The male's black wing veins are lighter and narrower than those of females. [155], Parasites include the tachinid flies Sturmia convergens[156] and Lespesia archippivora. Tagging information is used to study migration patterns. For the average home butterfly garden, this scenario will only add more OE to the local population. [86], Additional studies have shown that different species of milkweed have different effects on growth, virulence, and transmission of parasites. [147] There is also evidence that monarch larvae living near roads experience physiological stress conditions, as evidenced by elevations in their heart rate. Males are slightly larger than females[10][25] and have a black patch or spot of androconial scales on each hindwing (in some butterflies, these patches disperse pheromones, but are not known to do so in monarchs). [54] At first, its exoskeleton is soft and fragile, but it hardens and becomes more durable within about a day. [79] Like humans, their retina contain three types of opsin proteins, expressed in distinct photoreceptor cells, each of which absorbs light at a different wavelength. However, with less tourism, monarch butterflies will have a higher survival rate because they show more protein content and a higher value of immune response and oxidative defense. Once the eggs hatch, the caterpillars are poisoned by the toxicity of this invasive plant from Europe. It is grayish white in all areas of its wings that are normally orange and is only about 1% or less of all monarchs, but populations as high as 10% exist on Oahu in Hawaii.
